i am very sure you wont.

 

I said because I HAVE. Bent my frame with LESS than HALF that weight.

Setting 7400lbs on the truck is one thing. Now drive it with that weigh an hit bumps.

Putting an a WHOLE other truck just on the rear of a pickup, is a sure fire way to do some carnage

 

you bent your frame with half that weight, 3700 pounds, on what truck? my 92 f150 has had 3521 pounds of wet fire wood in the back, this was scale verified, meaning i drove over bumps, and the scale was down a dirt road that had bumps worse than any paved road i have been on. i actually jacked up the truck and ratchet strapped a piece of wood (it was what i had available) so the frame set on that so the bumps wouldnt slam things around. my frame is just as straight now as it was before i did that and remember its an f150, not an f250 like we are talking about on the thread

 

Right here. LEss than 2500lbs tongue weight bent my 1/4" frame

 

My 88 f350 drw is 4x4. F450s an above were 2wd only. They were converted with alot of marmon & herrington axle setups if im not mistaken. Sorry jus read chassis truck no bed 4x4 optionforget first statement. That being said, when i went to a drw i could not believe the difference in towing. It makes towing any amount of weight a dream.

 

wow, that is truely sad, my tractor weighs more than the truck you have on the trailer and my 150 frame is still straight, i think you got a bad frame out of the factory.... i hope but than again, a bumper hitch trailer has more leverage to work with also

 

you broke your truck already Brad! uh oh! id say your frame had issues.

 

Why so much tongue weight? To have that much tongue weight the trailer should weigh 25,000 lbs! I've towed 7000 lbs (scale verified) with my 88 F250 Light Duty and it didn't bend the frame like that.

 

the 10 percent is a general term, it all depends on the trailer, my one trailer only tows nice with less than 10 percent of tongue weight, and my small homeade one tracks straight as an arrow no matter how much tongue weight it has (i have tested it up to 50 percent tongue weight down to 2 percent)

 

Frame had ZERO issues. No cracks, no rot, NOTHING. I think some of my issue is the airbags adding a pivot point Ford did not have in mind. They wanted the suspension to take up the bumps, the bags would not allow that to happen. Then add in a 1000lb engine in the front and you have a bent frame

As for the 2500lbs tongue weight. Empty trailer is over 1000lbs tongue weight. Then put a 7500lb truck on the trailer and I have 2500lbs tongue weight. Trailer weighs approx 5,200lbs and the truck weighs 7500lbs So I was grossing out at a lil over 20k

 

the "will excessive weight bend my frame" argument is moot. if I always drive 15 mph over the speed limit, and havent gotten a speeding ticket yet, should I go around telling everyone they wont get tickets doing the same thing? does that mean I will never get a speeding ticket?

you can bend your frame with a lot of weight, or a little weight. you can bend your frame a lot, or a little with either, or not at all. is it a good idea to load excessive weight into your truck? not if you don't want to bend your frame, or highlight other weak links in the suspension, frame, etc. do a lot of people get away with excessive frame stress? absolutely. is it wise to advise others to exceed what the factory has indicated to be safe limitations of the vehicle (obviously the payload under plenty of different conditions is far greater than factory rating)? absolutely not. there are a myriad of variables that go into this equation besides weight alone, some of which are too specific to list in full.

something will eventually kill your truck. loading it carefully and paying attention to physical limitations will minimize the chance that a bent frame sends it to the boneyard before something else does. after all, we are talking c-channel frames that are only getting older.

p.s. i am in love that 4dr sb 4x4 dually, brad.

 

I doubt your frame has seen 2500 lbs of tongue weight (your avatar pic suggests you have very little tongue weight - i.e. you have a nice trailer and load properly/accordingly), your f150 doesn't have a giant anchor up front in the 7.3, and I would venture to say your ride height is not as high as his. also, unless you have an extended cab long bed, there is much more length to amplify the stress between his axles vs yours. there is hellofa lot of stress on his frame in that pic with that load setup. 2500 lbs is A LOT of tongue weight, im surprised the trailer and hitch didn't suffer as well/before the truck frame. turn those trucks around and put the engine on top/behind the axles!

 

I don't think you have driven a new truck since...well, 1998. I've never been in a 235K truck that rides 'like new'.

As far as tweaking the frames on the trucks shown in the preceding pictures, a bumper pull hitch and all it's tongue weight adds MUCHO stress to a truck frame. Measure from the front spring hanger to the hitch. 60 to70 inches I'm guessing. Great big leverage action going on there. And with Powerstroke torque sent back to those big honkin tires, the spring wrap up is pulling down on the rear of the frame horns and the front of the spring is trying to go up thru the bed rails. I'll bet if you look closely at frames that have been tweaked, it all happens near the front spring hangers.

As far as rear axle capacity is concerned, my 2006 F350 dually has a rating of 9000#. I've been there and more as I used this truck as a lightweight freight rig for two years. Dual rears do add some stability and increase payload capacity.

If this link works, check some of the loads I documented.

 

Whoa...I think I might have set off a small powderkeg with this thread lol. Surely not my intention.
