Topic: How fast do you travel loaded?

Posted By: dave17352 on 05/11/15 07:51pm

Just curious how fast do all of you TC people drive. In my case when I am fully loaded 3500 + truck camper and pulling my 3500 boat, I keep my speed no higher than 62 mph. My biggest concern is a blow out. I am at my trucks weight limits but not over. What say you all?

I keep it around 60 to 65 seems to be the sweet spot for fuel milage also.

Time is more precious to me than the fuel savings. I always have a trailer & I drive 70 mph +/-

62 -63mph most of the time BUT I would not drive these speeds with out a Valentine Radar and a CB radio to keep track of the "SMOKIE BEARS" ahead and behind of me. When you start driving about 63 mph or more you are passing a lot of 18 wheel trucks and it makes your speed noticeable to the "Bears".

The truck says 65. The GPS reads 62. A safe speed for me.

It depends on the roads, but not usually much over 70. Normal to save fuel is about 65. I prefer scenic routes for the shorter trips, but for the long highway stretches 60 vs 70 can be hours different not to mention for the fact that you would be essentially a roadblock and cause an unsafe position when many people could be driving 80. Last weekend was an exception, but I drove almost 1000 miles.

I always go the speed limit due to our single lane highways up here. 55 most places with a few 65 stretches. It is illegal to impede traffic or hold up more than 5 vehicles on some of our roads.

I really do not have a particular speed. For the most part, my speed depends on the road condition, weather and/or traffic. With side windsor rainy weather, usually 50 to 55 MPH. No winds and clear weather 65 to 70 MPH. There are times (not often) I just fee like poking along at 55 MPH. I have different comfort levels and stay within those. I might add, my speeds do not change much with just the TC or towing my Samurai. When towing I usually have to make a conscious effort to drive at 55, which is the speed limit in Calif when towing..

My 19.5s are speed rated for 82, I usually drive 62-65 but generally my max is 70. Now if I am towing horses you will find me in the slow lane going about 58 wave as you go by.

It seems that I have all the intentions in the world of keeping my speed on the interstate at 62 to 65...but it creeps up...especially when you get south of Olympia, WA...it goes to 70 and soon I am cruising along...then it creeps up again! But that is when I have a destination and a sort of time table...on go no where in particular that day trips...it still creeps up, but it takes a little longer...then I notice it and drop back down and the cycle starts again. But I tell you the truck, tires, motor, boat trailer seem to like about 69, just settles into a groove! AWAY WE GO!!! Once in KS I did 90 for a few mins, long flat straight.

Posted By: Bedlam on 05/11/15 10:00pm

I keep my speed at or bellow 65 mph. I wouldn't make up enough time to counter the fuel waste of driving faster and many times I'm towing a trailer with 65 mph ST tires. If the speeds are slower, I'm typically within a couple mph of the posted speed in the right lane unless I am passing someone not sustaining that posted speed. Naturally, weather and road conditions may have me driving slower than posted and I fall into the slower flow of traffic.

Interesting you ask, as I was wondering the same thing. I drove to Kearny Wednesday at 62, and I bet 500 to a thousand semi's passed me like I was standing still. Returning I went 65, and very few passed, plus I actually passed a few myself. I rarely go over 65 unless passing, driving a top heavy TC just feels unsafe. Driving a car I am usually 1 or 2 miles over the limit.


Posted By: whizbang on 05/11/15 10:08pm

2 or 3 mph under the speed limit.

45-55mph, depending on terrain and road type. If I hit a good grade, I've dropped down to 30-35 mph on more than one occasion, as the truck simply couldn't pull the grade any faster.

I'm flexible but normally 65 to 70. With just the camper on on a long trip we will go the speed limits, if we are flat towing the jeep I'll stick to around 60. Of course road conditions trump everything else.Sometimes we will be the ones slowing everyone down.

It all depends on the road conditions, wind, traffic, etc. A life, mine or someone else's, is not worth the few minutes that driving like a crazy person will save me. I have been to a lot of accidents where someone thought that it would never happen to them.

Tend to keep to 60 on the speedo on multi-lane highways, though the GPS reveals that is really 56. That is the speed limit for commercial trucks over here in Europe so it means I'm not holding up those who have to earn their living at the wheel. I've done nearly 80 in the truck before, but you can almost see the fuel gauge move once you get much past 65, and diesel over here may have come down in price, but it is still around $2 per liter.

60 for mpg






Posted By: fitznj on 05/12/15 05:07am

Under perfect conditions - then I stay to 60-65; When traffic builds up, then I'll slow down a tad - speed is not the issue when towing - it's STOPPING.
I've locked up the trailer wheels on many occasions when someone jumps into my braking zone and slams on their brakes...... (probably the biggest item of stress when towing);

65 MPH - unless I am traveling through a major city such as Dallas or Kansas City and then it is whatever it takes to keep from getting run over by all the drivers that appear to be qualifying for the Indy 500.


Posted By: PRodacy on 05/12/15 06:41am

We nearly always drive the speed limit - around 75. Driving 60 or 65 is just inviting someone who's not paying attention to rear-end us. Our rig handles the same at 75 as it does at 60.

Usually 65 or so, but up to 75 at times. Too much noise and fuel consumption to go faster.


Posted By: ralphnjoann on 05/12/15 07:03am

The only time I exceed 55 is when is when I let my attention lapse while going downhill.


Posted By: joe123 on 05/12/15 07:11am

I never go over 55 miles per hour, with the load it takes more time and distance to stop in an emergency, lots of wild life up here in Canada.


Posted By: mooring product on 05/12/15 07:33am

70 is my average speed. 80 if crossing Alligator alley. Now on our trip to New York I caught my wife doing 90 through South Carolina. It was 3am and I was sleeping in the passenger seat. She was running with three 18 wheelers, drafting them. "Slow your roll women!"

Although I agree with you. I work full time and don't always have as much time to make a far away destination as I would like. When pressed for time, I keep the speed down but reduce the amount time I am stopped. I find I make better time if I stay rolling instead of turning a 15-20 minute fuel stop into a 30-60 minute delay. I plan for 500 miles on a long travel day which will typically take 10 hours with included stops. We have covered more distance or driven longer, but then it is no longer a vacation for us. We try to make our vacation the entire trip from when we leave home to the time we return, not when we reach the destination and leave it.


Posted By: 6pac on 05/12/15 08:34am

We usually try to maintain between 55/60 . That's the best milage for us . Of course we ltravel mostly on flat ground . When mountainous traveling things change!

62-63 MPH. Up to 64 if on smooth interstate with a tail wind, rarely up to 70 when I have to pass someone driving 55 or so. I find if I try anything much higher my gas mileage plummets - not to mention the tires are rated for 65. I make sure to check inflation every morning before leaving.


Posted By: Jfresh on 05/12/15 09:15am

It all really a mind game I think when it comes to mpg and time. The difference between 60-65 mph on a 300 mile trip is what 23 minutes. Same with Mpg. The difference between 9-11 on a 300 mile trip is like $18 bucks.

I can tell you though coming from a TT and a underpowered Ford to a TC with a Ram there is a huge difference between 55 and 70 mph on long destination travel.

It depends what the speed limit is.

OR freeway max is 65 so I go about 65.
OR two lane road max is 55 so i go about 60.
WA I will go the speed limit of 70 on the interstates.
When we hit ID and UT with the 80 speed limit I keep it about 72/73 which is the motor turning 2k rpm.
Time is too precious for us to go much slower.

Here is my math for two weeks ago....driving from Moab, UT home to Keizer Oregon in one day.
1080 miles at 75mph equals 14.4 hours
1080 miles at 65mph equals 16.6 hours

One day driving back, not hauling the camper but towing my enclosed trailer with 3 quads in the trailer, one quad in the bed of the truck. I stuck to 80 in UT and ID where legal, hit Oregon and did pretty much almost 75 all the way to Portland.... [emoticon] my buddies and I wanted to get home to our wives after riding quads for a week in Moab.

I don't drive when I'm loaded either... [emoticon] but when my truck is, at least with the last few campers I've owned, I drive just under the speed limit, or 65 up to 70mph. I Hit 75mph once in a while, though I personally prefer 60-65mph. I try to just stay with traffic or get out of the way.. I have yet to take my current rig out, but will probably keep it around the same.

Just drive safe and be aware of what is going on around you ..

Life is more precious to me than time, so my usual interstate speed is 60 mph. If I notice traffic is being held up by me, I'll usually take a break but that has only happenedonce. My preferred back road speed is about 50 mph though I don't mind running about 35 either if there isn't much traffic on the road.

I have found I prefer staying a bit closer to home or taking more time to get there.

And yes, I still work full time with limited travel days.

I had been pretty much doing 65 mph, slower on hills, etc.

While doing RV transport over the same route day in and day out, I started to adjust my speed to see what effect it had on my MPG. It has a drastic difference, so my new mode is 60-61. I've been up and down 395 in Washington doing RV hauls, as well as back and forth on I-90 with my own trailer (not my camper) and have never been a hold up to traffic.

ST trailer tires are rated at 65 mph, so I really don't want to push the limits of the craptacular ST tires.

I keep it under 62, due to strain on the equipment! I wonder if speed has much to do with excessive maintenance issues?






Posted By: Jfet on 05/13/15 09:31am

Don't get behind us, we are going to be slow pokes unless we upgrade our truck. At 19,500 pounds and pulling a trailer, with a 200hp diesel we are going to be lucky to make 40mph up hills and 60mph on flat.

That being said, we get about 12mpg at 50mph and 9mpg at 60mph. An extra hour of driving slower for the same distance traveled, but you save 10 gallons of fuel. At $3 a gallon, that is $30 an hour.

Getting paid tax free $30 an hour seems like a good job during retirement.

Posted By: Crumm on 05/13/15 11:18am

3mph over the posted speed limit for me. I feel that 58 in a 55 zone is safer than having every impatient idiot on the road passing the slow RV in very unsafe places. People don't seem to use good judgment when passing a slower vehicle and I don't want to be next to the head-on accident they cause. When it says 65 I go 68 to stay with the flow. If your tires, truck, trailer or skill can't safely maintain something close to the speed limit you might think about upgrading. You wouldn't drive a moped with a 35mph top speed on the freeway would ya?

I go too fast and don't realize it! Damn Duramax, at 11.5K the load is nothing to that engine and rig can even accelerate from 75mph on long highway uphills. I do try to keep it around 65 though as fuel consumption falls way off after that with the massive wind resistance with the TC. I do stop though and check things to make sure wheels/tires are never hot.

i try to drive the sweet spot for my set up, regardless of the way the rest are driving. That sweet spot moves around though. On the flat with no head wind I like 64 mph. If driving into a headwind or uphill i'll just follow the sweetness and drop to around 58 mph. It all has to do with throttle position resistance; something you feel.
The woe is that my speed is usually faster than the trucks in the right lane and slower than the cars not in the right lane. So, I find myself weaving in and out of the slow lane more than I would like.
Peak torque on a gen2 Cummins H.O. engine is 1600 rpm, 55 mph on the speedo with stock tires, but the sweet spot for this particular engine is around 1850-1950 rpm.
If I'm in a hurry I'll drive 70-75 and stay up with left lane traffic with a slight deterioration of mpg. We just got back from a 1600 mile road trip in the TC, and averaged 12-13 mpg. Several times we paid less than $3 per gallon for No. 2, but it averaged around $3 per. $2.59-3.09 per gallon was the range.
Our traveling weight for this trip was 10,400 pounds. No trailer. No jacks. We were out 5 days and overnighted in sundry locations both in Seattle and rural spots in OR.

I'm really disappointed about how little time I'm saving after I double checked the math. Even doing an insane trip like last weekend and driving almost 1000 miles, I only saved 2.4 hours from 60 compared to 70. 14.29 hrs at 70 or 16.67 hrs for 60. I'm not sure how much that helped. [emoticon]

Unlike some of you though, I have absolutely no issues going up any of our mountains as fast as I want. [emoticon] I guess that's part of the issue.

I like to travel at between 55 - 60 mph. I like 60 mph as it is a mile per minute and makes figuring out how long it will take to get some where a breeze.
I try to stay off the interstates as I always find my speed creeping up.
I have been as high as 80 mph where it has been allowed and keeping up with the flow.
I normally have lots of time when I am travelling so I it pays to go slower.

Thanks for all the responses to this question. My main concerns are MPG and also safety issues in case of a blowout.

Speed is not the only factor concerning blowouts! Load and tire capacity. There is tons of discussion about LT tires and getting better load rating plus changing to 19.5's! Do a quick search, it will pop up.
Drive safely!

In a way, it comes down to a "time verses money" thing.
Driving faster costs more, so is the extra "time" at the "destination" worth the cost of more fuel to get their faster?
Maybe so, maybe not. Everyone places a different value on their time, and their money. LOL.

I've found that by slowing it down a bit, I'm not as exhausted when I get to my destination.... especially on less than perfect road surfaces. The faster we drive, the more beat up we get on rough roads.

I keep it under 2k RPM. ANything over that and I get worse fuel mileage.

At 2k RPM I'm about 70 mph. So I keep it at or under that. I get 12.7 mpg with the camper only, around 11.5 with the Jeep on the trailer also.

Posted By: spacedoutbob on 05/14/15 08:25am

I usually stay at around 55 to 58 mph. I'm in no hurry, I figure that it will still be there when I get there.

You figures are interesting. They are exactly the same as mine, camper only and flat towing my Samurai.

I do 70 mph at about 1800 rpm. I have a 1996 Dodge 2WD dsl 12-valve with a highly modified fuel system.

Reading these post, I don't think anyone mentioned years back when the National speed limit was 55 MPH. I find it interesting that not I am much older I really do not have a major problem driving at 55. I sure did back then. Now, my speed varies due to road conditions and my mood.

Heck, when traveling unloaded, I travel through a number of places with 80 mph speed limits and can't bring myself to drive that fast even rolling empty.

Just curious has anyone had a blow out at freeway speeds?


Posted By: Reddog1 on 05/14/15 11:21am

I have not had a blowout since I stopped running recaps and may pops back in the late 70's. Actually, I guess I am pretty lucky, only one flat in over twenty years.

Yes, our old '99 tent trailer, about 5 years ago, one tire going on vacation, other tire coming home, Tires were at least 4 year old. Both went on I84 in Oregon going about 65. Got new tires at Les Schwab and no troubles (sold a few years after that)

On my enclosed trailer on 2 year old tires about two years ago, had one explode, we heard the pop, and then pulled over, Sheriff was behind me and gave us an escort to the side [emoticon] About 3 months later another one went. After the second one, took them all to Les Schwab and they pro rated me into a new set of a ''Max Tow'' tires. LS said they actually had so much trouble with the set I popped that they stopped carrying them. A friend of mine with the same tires had two blow outs on one trip and exchanged his in just Like i did. All flats on I84 in Oregon going about 65.

Trouble free on trailer tires now for 12K miles and a couple years.

Dually truck handled the flats like a champ. Camper was on the truck with all the enclosed trailer flats.

I had a valve stem fail on my Opel while driving over 100 mph in Germany. I thought something let go in the front end with the way the car shook, but I let off the pedal and coasted on to the right shoulder. My other flats at speed have been leaks where I felt vagueness in the road feedback and have been able to safely pull over (whether towing or not). Most my flats at speed when loaded destroyed the tire integrity requiring a new tire even though the tire did not shred. We had a popup trailer that liked to eat tires, but it was light enough to pull off to the side of the road without even having a tight grip.

Road Speed--- this whole thread has been beat to death[emoticon] There is no right or wrong answer, it boils down to what each RVer is comfortable with. Or, as Mark Twain said "How long should a man's legs be---answer--- Long enough to touch the ground[emoticon][emoticon]

Yes, but not on the truck while a camper was on it, Several spread out over a lot of years. One happened coming down 17 from flagstaff to phoenix. I had a TC on a 68 1/2ton chevy pulling a 2 horse trailer with tandem axles. It didn't effect the truck at all and I had no problem pulling over.
I have had a blow out on our 16ft BP flatbed and on our 24ft GN Flatbed each was overloaded with ceder logs and had old tires. The truck was empty each time and I had no problem controlling it.
The worst blow out with a trailer was on 395 coming back from camping above Bishop. I was moving along in my 56 1/2 ton chevy with my canvas sided poor mans camper. Just some wooden stakes with a tarp stretched over them, and all my camping and horse gear in the bed. It was a single axle trailer. When the tire blew the trailer tried to jack knife, I could see the side of the trailer in the mirror. It was no fun but I got it pulled over all in one piece. That little 1/2 ton held it ok.


Posted By: jimh406 on 05/14/15 04:19pm

I've had a blow out on a rear for a 32 ft Class A with dual rear wheels. In hindsight, it was probably underinflated and overheated from the hot day, but I can't say I checked the other tires. I was lucky and one exit from a known tire shop, so I drove there instead of trying to change the tire on the side of the interstate.

It was very loud and damaged the inner liner, but it was a minimal loss of control.


Posted By: acudr on 05/16/15 10:43am

After reading this, I am on the faster side. What I pay attention to is the feel and engine sound. Dodge 2500 CTD... N*TC800. Maybe 12k lb total. The diesel hits this sweet spot 1900 rpm. Speed is 69 - 70 and the ride is smooth.

Posted By: geekbstrd on 05/17/15 08:40pm

I have done 78 but it didn't feel very comfortable. 65 is pretty good in wyoming. Interstates in the west are easier than the east in my opinion. My Northern Lite is a little rear heavy which makes my truck handle worse than normal. I'm working on some front end issues that the previous owner of the truck created when he lifted the truck. Just mentioning that for others who may have lifted trucks.

65 mph on I5 with a Lance 1055 in the bed with LT tires rated at 3750 pounds

hell of a ride and $3500 worth of body damage. I switched to 19.5 wheels and tires rated at 4500 pounds each soon after

60-62mph I get 16-17mpg with my 2001 Dodge 2500 diesel...........any faster doesn't make sense to me.

Like others said, I'm not in a hurry and I just assume keep my family alive.

"How fast do you travel"
The speed at which I travel when towing my RV is of little significance IMHO[emoticon] What I am more concerned about is how quick I can brake my RV to a safe STOP!!!


Posted By: TCdude on 05/18/15 02:29pm

Depends on Road...speed limit mostly

downhill in a 65.. I'll do 75
Uphill in a 65... I'll do 45 towards the top

I just completed a 4200 mile trip from MN to FL and back and actually saw little difference in fuel mileage whether doing 60, 62, 65, or 70.

In traffic just keep your distance and drive safe.

I see about 2 to 3 mpg difference from 60 to 70.


Posted By: Jgwoods on 05/18/15 07:08pm

Diesel fuel mileage hasn't varied much once I am loaded up on my 2013 F-350 DRW. In Utah I set the cruise control to keep up with traffic at 95mph and I got 11.4mpg over about 50 miles. Speed limit was 85.

Normally I drive about the spped limit to 5 over and get 11.7mpg, maybe 12.

Road conditions are a big part of the decision- if everyone is going 70 I do too. If the road is busy around rush hour or its California then I tend to keep right and run with the crowd.
