Were running a 2004 f250 supercab 4x4 with the v10 and 3.73 limited slip, have been towing a 32 foot 5th wheel with dry weight of 11000 lbs. I just ran into a sweet deel on a 36 foot 5ver but dry its 14200. lbs Am I okay or do I need to regear to 4.3 will that be okay? or Do i have to pass on the deal.

 

You are already over rated max at 11k (unless it's a dualie) and a gear swap won't help you, even a dualie can't handle the new one. You need a F-450 to pull that thing.

 

The truck can pull it and handle it decent. I've seen worse.. That would be on the edge with me and a V10. I know my dad has an 03 CC SB v10 and he has a 28 and a 32 5ther and it handles them just fine. Just the tranny holds either 3 or overdrive too long when pulling it. Rather then that it pulls and stops just fine..

2004 Super Duty F-250/350 — Fifth-Wheel Towing
d = 3.73:1 axle ratio
f = 4.30:1 axle ratio
i = manual transmission
j = automatic transmission

F-250/350 SuperCab 4WD SRW 6.8L V-10 9,900 d,i
F-250/350 SuperCab 4WD DRW 6.8L V-10 9,600 d,i
F-250/350 SuperCab 4WD SRW 6.8L V-10 10,400 d,j
F-250/350 SuperCab 4WD DRW 6.8L V-10 10,100 d,j

So, best case is 10400. He's already over that with his 32 footer DRY. Now you say he's okay adding another 3400#? I don't think that's a very good idea.

Now, regearing to 4.30's will NOT legally increase the load ratings, but here is the same truck with 4.30's:

F-250/350 SuperCab 4WD SRW 6.8L V-10 13,400 f,i
F-250/350 SuperCab 4WD DRW 6.8L V-10 13,100 f,i
F-250/350 SuperCab 4WD SRW 6.8L V-10 13,400 f,j
F-250/350 SuperCab 4WD DRW 6.8L V-10 13,100 f,j

Still over max load, dry.

 

Well if you're not comfortable pulling it then don't. I was just merely sharing my opinion. BTW does everyone go by the books. Even thoe my truck is a 05 6.0 and is different from his, I pull 13K off the rear and more then 15,500 off the GN. And I feel comfortable doing it. He asked if he would recommend it and I said that is getting close. Its not like he's pulling a F450 load behind it.

 

Cops, Judges, and undertakers do.

 

It may pull it ok, but if DOT makes him run across the scales, he'll be SOL.

 

DOT here is strict but mainly on larger trucks. I never see a camper puller pulled over. As long as your GVW is under, tires are of the correct load range, lights work and have the safety chains/break away cable is hooked you should be fine.

 

But that won't be the case here.

 

To all that answered my post thank you, although I agree my truck could pull it the deciding factor was if I was in a accident and somebody died ccould I ever look at myself in the mirror without thinking my being over weight caused it... so with that in mind bought a 2010 F350 6.4L Deisel Duelly 4.1 gears boy is she pretty and can tow a 18000 lb 5ver
