RE: Frame Stiffing to reduce Porpoising?

I'm betting facebook guy thought nothing of his 2" of flex too... I think Facebook guy's frame was flexing a lot more than 2". From what I have read, he was overloaded at least 1500lbs, maybe closer to 2000lbs and he had a huge moment arm created by the bikes hanging off the back like they where. EBikes weigh close to 100lbs, he had two of them so he's got 200lbs that was nearly 8 feet from the center of his rear axle (rough guesstimate). That is 1600lbs of moment arm pulling on the frame. That coupled with rough roads and lots of miles seems to be what did him in. Other's have studied and argued his situation way more than I but from the little I have seen, it doesn't surprise me what happened to him. The center of gravity of our campers is generally very close to right over the top of the rear axles or just a bit in front. This means the center of the frame isn't supporting our four to six thousand pound campers. Most of that weight is transmitted directly into the rear wheels. However, the frame is having to "balance" or keep in place a heavy engine up front over the front wheels and the heavy camper on the rear wheels. The frame flex we observe is more due to the frame keeping these two heavy pieces together going down the road. Having the camper weight slightly forward of the rear axles puts the center of mass between the front and rear wheels such that the frame is dealing with the frame flex occurring consistently between the front and rear wheels of the truck. This is an ideal situation and what the engineers design for. If you add a huge moment arm off the back with a heavy trailer along with a hitch extension you are now adding a rearward twisting motion to the frame. So now you have competing forces that the frame is dealing with, almost like a teeter-saw. I would venture that the amount of frame flex Facebook guy's truck endured was significantly more than is common for a properly balanced truck. Finally, rigidity isn't everything. I know I started this post asking if frame stiffening was something others had done. However when you make something rigid, you lose the ability to flex without causing permanent deformation. As others have said, this deformation causes fatigue over time and leads to frame failure. The engineers that designed the truck obviously know this but what we might be seeing is that the increased rigidity of the frames is causing overloaded trucks to deform and fatigue the frame material versus just flexing like the older and more flexible truck frames of the past. As campers continue to get heavier and truck frames continue to get stiffer, we may see a lot more Facebook Guy's in the future. good analysis of the Facebook guy. Also the thread is great as usual. Something I have integrated in my local travels that sort of go along with what we are talking about. I tow a small 4x8 trailer now almost everywhere I go. My 1181 is so ass heavy it's not a pleasant drive anymore. I put my two small generators, Two spare tires, tool box, spare parts and anything that had weight in the camper to the trailer. On top of everything else I've done it has improved the ride. One more thing, You guys go back and forth about many things and you get very frustrated with each other from time to time. For a guy like me that wants to hear all sides it's very helpful. I don't post much but I read everything every day.

RE: Frame Stiffing to reduce Porpoising?

But a very important point that maybe scooby just brought up is the amount of movement in the overhead portion that we ALL see from time to time with big TCs is not necessarily indicative of excessive frame flex, nor is porpoising. Unless it’s literally a rocking horse most or all of the time. Which is more likely suspension and shocks. Given the camper weight and configuration changing is not an option. Perhaps my use of the word porpoising was just the wrong terminology and that set you off. What you are describing is what I am observing. The camper overhead rocking slightly up and down on rough roads. When that happens, I can look in the side view mirror and what I observe is these lines flexing ever so slightly. https://i.imgur.com/F1RGtDCl.jpg Now, I don't have a way to measure it, I guesstimated 1 to 2" but probably more likely in the less than 1" range now that I think about it again. So, everyone else, while you are driving down the road and come across a bumpy section and see the overhead portion moving up and down, take a look in your side view mirror down this sight line and I am betting you will observe some movement as well. Happens all the time...

RE: Frame Stiffing to reduce Porpoising?

Got a question for you seasoned drivers with older rigs. I have a 1999 F350 Dually Quad Cab Long Bed. I've been driving it for thousands of miles and for the most part, it's been fine. However, while driving on rougher roads, I do get a porpoising effect happening. I can look in my rear view mirror and see the frame flexing at least an inch or two. My camper is the Bigfoot 2500 and with everything loaded up is probably in the 4500lb to 5000lb range. According to the sticker on the camper the center of gravity is almost exactly over the rear wheels. Now the center of gravity does change with water in the tank as the fresh tank is in the front of the camper which puts it at the front of the bed. The porpoising isn't a "problem" in the since that I am concerned about it causing damage. I'm well within the carrying capacity of the truck. That being said, it is an annoyance for comfort and drivability. I have already replaced the shocks on the truck and that has helped somewhat. I am also looking and seeing that I probably could move the camper another inch or two forward when I load it. I don't think this will make much of a difference though. So, my next thought was to look at having my frame reinforced. I know there are all sorts of complications when going this route though. Ford does fully boxed frames for a reason because it gives so much more rigidity. I no there is at least one person that has done this on their 7.3 from a posting on the Ford forums. This is obviously a huge expense and extreme measure. Has anyone else gone through this or found a way to handle excessive porpoising on older C channel frame trucks? I drilled many holes into my truck frame over the years and was concerned if I changed the original weight rating. I went to a welder shop and the man said it was possible but unlikely given my truck was built in 1996. He said trucks are built differently these days and would have answered yes to my question if I had a late model truck. He filled the holes with welding material and welded a small plate over the spots at my request. I feel no difference what so ever. I hope this helps. My main problem was the front end was too light as the previous owner decide to cut away most of the steel for a custom hood. Again, I feel no differenc.

RE: Broken Frame on a RAM 3500

Some of the camper weight ratings I have seen assume a 150 lb person in every seat. If you have six seating, that reduces your camper carrying rating by 900 lbs. Chevy does it this way. I have a dually crew cab with 3 seats front and back, that's 900 pounds. This is probably the best thread I've read and participated In on this forum. The weight police pros and cons be darned, truck camping takes some thought to be realistically safe on and off the road. As we all see the price is really something. JMHO

RE: Broken Frame on a RAM 3500

The comments under the article "On the article page that was posted by the op" are very close to the discussion we are having here... In my very limited knowledge of metal there are two things that could do this and they are weight and rust. If a bridge over a stream rusts it falls apart over a very long period of time. Another point is with my unloading of every single possible pound of weight I got the weight of my 1181 down to 4300 lbs from well over 5000 lbs and it still feels like the front end is driving up in the air. JM2C Great discussion though and you are all correct about your points.

RE: Levelling blocks for camper on driveway with 2 degree grade

Also mix a little fine sand into varnish or another finish so they do not slip when stacked. Hey Jim, Did you ever post a pic of these blocks?

RE: Shadow Cruiser Truck Campers

Thanks for all the advice. What model are you looking at csh, I'm retired and have time to surf. Maybe some more info....

RE: Shadow Cruiser Truck Campers

I agree with Grit dog. If it's in good shape it's worth what your interested in paying for it. I never had one and I don't recall a ton of info out there because of it's age, but here is some info I found. https://www.wanderthewest.com/forum/topic/10612-shadow-cruiser-truck-camper/ https://www.expeditionportal.com/forum/threads/shadow-cruiser-pop-up-truck-camper-1800-or-open-for-trade.114377/ https://used-campers.forsale/shadow-cruiser-truck-camper/ https://www.rv.net/forum/index.cfm/fuseaction/thread/tid/27857674/print/true.cfm https://www.rv.net/forum/index.cfm/fuseaction/thread/tid/29350194/print/true.cfm There are many more links just to get an idea, Cheers!

RE: Slide when mounted to truck

If I'm level, I put the slide out. You can unlock the tiedowns to help level. We almost never unload the TC while traveling. Times two! You can also level with the orange leveling blocks, place them under your tires and drive on. they help a ton.

RE: Camper looks like its not level

Mkirsch usually isn’t so much use or obtuse. He’s a good guy, but I got the same vibe as you. That said, if the previous 5 pages doesn’t give you some more ideas or context, then likely the future responses won’t either. It just wasn't clear to me what the ultimate solution was. It appears that crowning in the bed can cause this, but it's just not clear. I'm going to get a borescope and see if there is indeed a gap at the front of the bed when the camper is in that would indicate that it's riding on a crown and tilting towards the rear. I'll report back. There really wasn't a solution just more of the same back and forth. I posted some pics and after that I tried to get it perfectly level but with no luck. My Chevy bed is slanted to the rear and closer on the sides in the rear than in the front. That was my answer. Good luck with yours!

RE: Lance 650 - Anyone try upgrading battery capacity?

From someone who does not have a Lance 650 I can pretty much say that any mod is possible. I have been in a 650 and they are beautiful but the prime reason for the 650 is weight related. Realizing that your putting in lighter weight batts and acc. it will still add weight. I looked at you profile and didn't see a truck. I'm just pointing out the obvious situation for the 650's existence as well as it's resale situation. Just sticking my nose where it doesn't belong. Welcome to the forum! Definitely, I'm getting the truck based on the camper (most likely 1 ton) and am torn on a Lance 650, Northstar Liberty or Palomino HS-690. I want something small and light for the truck as all of my camping will be off grid accessed by moderate trails. So it's coming down to how easy to modify these are for sustained off-grid use. Adding solar, upgrading batteries, swapping inefficient appliances, etc... The HS-690 finish quality (despite being aluminum frame) is scary and i've almost ruled it out for how quickly i'd expect it to fall apart. The "windshield" also felt dumb and impractical for winter camping. The Lance's quality felt superb and had the great size dinette, but the mechanical compartments already seemed maximized and taken up. We moved to central Florida 7 years ago and the trips have been getting shorter and shorter with the truck and camper getting lighter and lighter. 3 hours tops and pop a beer. We used to drive from Binghamton NY all the way to the keys. It's a long drive..... As I become more comfortable with the Florida lifestyle and Florida truck camping I too am looking to downsize big! We often go out to New Smyrna Beach and watch the Toyotas "smaller trucks" with their pop ups park on the sand. They stay all day with all that they need. I'm always looking at very small truck camper rigs with enormous boats in tow. Will I finally part with my 1181????

Welcome to the forum! but he is replacing a heavy battery with a lighter battery... I thought he was adding a battery to up his amps? He also wants to remove the vented battery box I believe to use greater space for more stuff. I simply never know what I'm talking about and that should be widely known by now.

RE: 36" Hitch Extension for 2" Receiver - Are they Made?

I wanted to share a couple of pics of the TL Super Truss 36" LOWER support bar. The 5/8" hitch pin hole was drilled incorrectly. The hitch pin hole was approximately 5/16" off center on one side. This is poor quality control and should be embarassing for TL. Contacted them and sent pics. Awaiting a response. https://i.imgur.com/m1L00nGl.jpg https://i.imgur.com/7n1uun3l.jpg https://i.imgur.com/tVlxjaXl.jpg I agree that's ridiculous!

old Atwood jack motor

Hi, I was surfing around tonight and found one of these. It always seems that every few weeks someone is looking for one. Just posting some info to a link. https://www.rvsurplusparts.net/75391-atwoo-electric-motor-kit.html

RE: 36" Hitch Extension for 2" Receiver - Are they Made?

How can this be solved? What others done with this dilemma? Spend more money than he was planning. Unless the trailer is tiny, tiny and super light tongue weight...36" out is massive for 2" only. Super hitch is where just about everyone ends up...even those of us that weld and fabricate. I would think the class three hitch would be a problem as well. I do not think it's designed for that kind of up and down tork.

RE: 1977 Sunline Truck Camper FULL BUILD

MISC EXTERIOR - Truck Camper Build Part 46 Is there a reason for the different colors of paint you use at different places of the camper or just what's on hand. Green on the upper parts, white, some black etc... Sorry if you said something about it but I don't hear very well.
notsobigjoe 08/12/22 03:01pm Truck Campers
Sometimes genius needs to be recognized.

Of course I could never get my Fat --- in that little closet but for a couple of kids starting out I think it's a great idea!!! I also like the camper, I don't know why It kind of reminds me of a western theme type of thing and I think that's what they're going for. I like to post some cool stuff now and again.
