RE: Ford super duty 3.31 rear end. Will it be a big mistake. ?

I drive a 2012 Job 2 6.7 diesel. It engages engine braking when tow haul is turned on and no other time. In tow haul if you press the brake petal more than slightly, it will down shift to cause more engine braking. I understand that later years (maybe around 2015) the engine braking and tow haul modes were separate switches so one could engage the higher shift points of tow haul without engine braking involving aggressive down shifts. When tow haul and and cruise are both on the engine will downshift aggressively to try to maintain the cruise speed setting when gaining speed down hill. As said above, I'm in that model year range where engine braking was not very effective. However, if one sets the cruise about 10 mph less than the maximum speed that you want to achieve going down the mountain it will usually hold it back to that +10 setting. At least it will going down the South side of Mount Eagle Mountain. I don't believe that a 2012 does any automatic trailer braking. I have no idea how later years behave, but I cannot imagine that Ford would keep engine braking from working if one was driving without using cruise. Oh, and I was only indicating that I shut off cruise going down short hills where I'm only going to gain a few mph to keep the down shifting to half of what it would be otherwise. It will still down shift going up the other side. Apologies for getting away from OP's original question. Again, either axle ratio will be fine but I would choose the 3.55 because the 10 speed top gear ratio is so low.

RE: Ford super duty 3.31 rear end. Will it be a big mistake. ?

I run 275/R65-18 highway tires, so the 3.31 works (mostly) for me. My 800 torque and 400 hp works great as others have said above. Tow haul mode absolutely eliminates gear hunting—my transmission just drops to the gear needed and holds it. My comment earlier about dropping to fifth on hills was based on experience in states with rolling hills where little grading is done. My favorite complaint is I-26 in NW SC. The trans will drop to fifth going up, back to 6th as I crest, and shift back down to fifth going down with cruise control trying to hold the speed. Just a ton of shifting! Yes, I know the owner’s manual says to not use cruise when towing. I end up shutting cruise off going downhill letting it coast up a few mph. Just to answer the OP’s question clearly: no you’ll not make a mistake with 3.31.

RE: Ford super duty 3.31 rear end. Will it be a big mistake. ?

My bad on 20" tires requiring 3.55. Looks like the last year for that was 2019. I still wouldn't choose it for pulling a DRV. Not that it matters here, but the 6R140 does not have a 1:1 ratio. 4th is 1:1.15. I believe the Allison 1000 does have a 1:1 ratio.

RE: Ford super duty 3.31 rear end. Will it be a big mistake. ?

It would be handy for folks to read the 2021 Ford Super Duty Order Guide when determining axle ratios. The built my truck app on line will show ones choices as you build. Ford is fairly stingy on axle choices depending on model and options. For Instance if one gets 20” SRW tires, only the 3.55 may be selected with a diesel. We tow with a 2012 F-350 diesel 3.31 6R140. When we had a 9400 lb fifth wheel it was just fine. Now that we have upped to 12,700 lb, I wish I had a 3.55 because I drop to fifth going up hills in those states that don’t grade much. As said above, desired axle ratio is dependent on tire size and top transmission ratio. The top ratio of the 10R140 is about 6% lower than the top gear on the 6R140 and the 3.55 is about 7% higher than the 3.31 so I would definitely get the 3.55 given the choice—same engine RPMs at highway speed. That said, if buying off the lot and other things dominate the choice, the 3.31 will just run in lower gears. The transmission is a truck transmission and is built to run in lower gears all day if needed. 9th gear is just 9% lower than 10th.

RE: 2021 Cummins 1075 lbft peak torque at 1356 rpm

So, this is the second thread that I have followed recently where the higher torque rise of the Cummins engine is discussed as a good thing. I have tried to think through why that is good, and all I can come up with is that it reduces the need to shift to a lower gear as load increases. In the days of manual transmissions shifting was something to be considered. With automatic transmissions, no big deal. As said above a downshift in a 3 or 4 speed transmission was a big jump in RMP, and again something to be minimized. Modern automatics are highly reliable and can shift without a reduction of longevity. The 8 to 10 speed transmissions exist to achieve the best ratio for given load and speed, so they need to shift to accomplish that. In my Ford with its less torque rise and a 6R140 transmission, gear hunting is not a problem, but if gear hunting starts, locking out a gear or switching to Tow-Haul mode solves it. Also, in a torque wars world where all the engines are similar at low end torque, I am fine with the engine having less torque rise since that means more HP at the top end. Top end HP is what accelerates my rig up to speed the fastest and pulls the mountain the fastest in whatever gear the transmissions determines. The Ford 6.7 consistently excels in HP while keeping up with the competition in torque.

RE: Ford F-250 7.3 Gas Engine Axle Ratios

My opinion--yours will vary: Ford reference only. Back in the days of the 4R100 transmission with its first gear ratio of 2.71 launch was a problem. When Ford came out with the 5R110 they split the old 1st into 2 ratios with the top 3 gears staying the same ratio. With a new 1st gear of 3.09 launch was improved. The 6R140 went to 3.97; more improvement. The 10R140 uses a 4.615 ratio. It is hard for me to believe that launch would be a problem with any axle ratio.

RE: SRW Tires

My opinion--yours may vary. Most of below comes from knowledge of 2011 through 2016—recent years may have changed some of this, although I haven’t noticed much as I look at recent years documentation. The Ford Super Duty brochure showed that the F-250 used a lighter capacity axle from 2011 through about 2015. There was a great debate online with most contending that the same axle is used in both the 250 and 350 SRW for mass production cost saving. It is possible that the lighter axle was used for 2011 Job 1 250s to use up existing supplies from 2010. However, everyone now believes that the axles are the same from at least 2012 and possibly 2011. The F-250 is typically derated to 9900 or 10,000 lb. GVWR even though it can physically handle more. This allows insurance and licensing cost savings in some states. The F-350 since 2011 adds the auxiliary spring and that’s about it other than labeling. So, yes, in agreement with most of above, tires are likely to be the limiting factor. I have noticed in recent years that the 20” tires can get as much as 14,400 GVWR.

RE: Meds on the road.

90 day prescriptions generally require the Dr to write a 90 day script. You don't need to do mail order to get a 90 day fill. It is the insurance companies that set the amount of time that a script may be filled early. We have used GoodRx and Kroger Savings Club to fill ahead of schedule, and just did for 4 months away. It cost a little more in co-pays--a convenience cost for us. Any drug store will transfer from another regardless of whether they are in the same company or not. But you will then have to transfer back. The chains like CVS or Walmart probably make that easier.

RE: How will my new F350 behave in cold temps?

According to threads read on Ford sites, Ford discontinued putting a block heater in every engine starting with the 6.7 in 2011. Folks got caught trying to save money and ended up with no block heater to connect a wire to.

RE: Can you put diesel oil in a gas generator?

Diesel oil has additives specific to diesel engines including specific to the catalytic converter used on automotive diesels. Rotella now makes oils for gas engines with different additives.

RE: How will my new F350 behave in cold temps?

Based on my experience with 2012 Ford 6.7--doubt that what follows has changed: New trucks are probably shipped with 10W-30 semi-synthetic oil--it is good down to zero degrees. The engine itself is rated to start down to -10 without a block heater. Mine will kick off in the teens with no hesitation. OP might want to consider arriving up North with a part tank of fuel so he can fill up with the thinner Northern fuel. NEVER, EVER, use a fuel additive containing alcohol--too much chance of taking out the high pressure fuel pump and injectors. Ford makes Motorcraft branded fuel treatment and anti-gel fuel treatment--that's all I use, and it guarantees that it is OK for a Ford engine. The one year I used Motorcraft anti-gel it made the engine rattle more than the Northern thin fuel did already. It was never needed the other 7 winters in Indiana. I did use my block heater to baby my baby, but I never saw the oil temperature more than 10 to 15 degrees higher than the outside air temperature. Ford recommends idling for at least 15 seconds just to get oil circulating to the turbo. In my experience idling did nothing discernable to raise the engine temperature--only putting on a load by driving down the road would help. In teen temperature weather, not even my 20 minute drive to work would get the engine temperature up to normal. The best thing for cabin temperature comfort is the optional electric coil in the heater system. It worked great for me to defrost the windshield in teen weather.

RE: When is weight distribution needed?

My opinion--your may vary. Safety is not black and white, yes or no, true or false--it is a great big gray zone where each has to find his/her comfortable zone. The truck rating is a guideline by engineers. It may not be safe 1 pound under and unsafe 1 pound over. My son never used WD or anti-sway with his F-350 dually crew cab long bed truck--you CAN'T make that truck sway. Then one day he hooked up a pole trailer and loaded it with scrap poles from a construction site. He was careful to put the shorter poles on top close to the front to increase hitch weight. Pulling out on the interstate he swayed across 3 lanes--thankfully no traffic. He got settled down and then swayed all the way to the right berm where he stopped. We now think that too much tongue weight contributed to the sway. Now he uses WD and anti-sway with his 6,000 lb. camping trailer. Using WD will return engineer designed weight to the front axle helping insure better steering which in turn will help move the rig to the safer end of the gray zone. I agree with above saying why not do all you can to prevent sway. Also very important--Ford anti-sway (and maybe others as well) is an emergency reaction by the truck AFTER it detects sway. You don't want the sway to start.

RE: Axle Ratio, new truck

If the 10 speed heavy duty transmission can handle 1050 ft lb of torque from the diesel then it can well handle 475 ft lb from the 7.3 gas pushing a 3.73 axle. Also, 1st gear in the 10 speed is 4.615 up from 3.97 in the 6 speed. It's hard to believe that a 4.615 ratio connected to torque converter would have a hard time starting any load.

RE: Thor or Forest River - Warranty and reputation

When one gets a lemon, that brand is junk for life. Our first trailer (when we knew nothing about RV quality) was a 2005 Crossroads Zinger. It used the wrong gasket behind the windows that leaked constantly rotting the floor, supported the fridge with a screw into thin paneling causing the fridge to sink buckling the wall beside it, and running the gas line through the spring hangers such that the pipe got pounded flat when the trailer hit a bump (I swear this is true--all trailers built that day were recalled). So, never another Crossroads for me even lots of other folks like them just fine.

RE: banking when full timing

Our goal in retirement was to travel 90% of the time although Covid has slowed that down to more of a distancing in the trailer program. Either way we needed to do banking away from home. We set up all of our recurring bills to direct debit a credit union account in which we keep minimal money. To get cash on the road we opened an account with Ally Bank which was recommended by a personal finance magazine. At the time, they advertised many free ATMs and up to $10 per month of refunded bank ATM fees. We found the free ATMs to mostly be in stores with limited amounts of cash available per transaction--It didn't seem effective to me to make a special trip to a free ATM to get a little bit of cash. While using bank ATMs worked at first, soon the Ally card processor started blocking the transactions as potential fraud even though we were using the same ATM repeatedly with no real fraud. That got to be so annoying that we dropped Ally and went back to Chase (who has a strong presence around our land locked house and in the Eastern US) for our cash needs . In the days of Covid we have found that using charge cards frequently has dramatically reduced our cash needs so we hit a bank ATM for a big chunk of cash when we run low. We'll pay a bank fee someday if necessary, but it hasn't been yet. We maintain 5 charge cards in case one gets locked and never (as said above) use a debit card for anything but cash from an ATM because a hacked debit card can lock up your bank cash for several days. Note: your experience with Ally may be different; in our experience Ally just wanted to blame their third party card processor instead of actually fixing the problem.

RE: Mor- Ryde pin box

MORRyde pin box is a simple, low maintenance, easy installation. Can be purchased on line for a discounted price. You need to order per your trailer weight as 4 different rubber blocks are available for different weight ranges. We found the the MORRyde pin box reduced trailer chucking by about 50%. Later we added the MORRyde SRE4000 rubberized suspension equalizer. That reduced chucking down to 2% of what it was before. We highly recommend both. We hardy feel our 12,500 lb. fifth wheel back there, and we are convinced that the ride inside the trailer is more gentle on the contents. Note that we still feel the jolt from the truck hitting bumps. I have wondered if truck bump would be reduced by an air bag type of pin box. But, I have guessed that air suspension on the truck would be the most effective at reducing truck bump.

RE: LR E tow vehicle tire comparison

Had 3 sets of Michelin XLTs before they changed the name to Defender. I found that they had the most road wander of any tire that I've driven to the point that I found them dangerous. Everything else about them was great. On my F-350 the front tires wear off on both edges as if they are under inflated (they're actually over inflated by load.) I am currently running Cooper HT3s because they have a real heavy edges which should help with the wear problem. The ride is a little better than the Continental OEM tires, wear seems good so far, and traction is just as good as the OEMs.

RE: Question/help with pin box

My opinions--yours will vary: Cushioned pin boxes will help reduce chucking transmitted to the truck. A cushioned suspension will reduce shock to the trailer and reduce chucking to the truck. In our experience adding the MORRyde pin box reduced checking 50% and their SRE4000 rubberized equalizer reduced it to a total of 98% gone. I suspect that the equalizer first would would have had a dramatic effect by itself. I strongly believe that reducing the shocks to the trailer will help it last longer before shaking apart. Pin boxes with vertical motion dampening may help reduce the shock felt in the truck--I have no experience.

Also long bed never needs a slider hitch. Sliders tend to take up even more bed space.

F-350 SRW Crew cab short bed. 37' fifth wheel is rock solid. Like above will go long bed for storage if we last long enough to need another truck.
