I pull the same camper with an 04 dodge 1/2 ton, hemi, 3.92 rear end, off road package, and I have E load range tires. I am rated to tow 8500 so I am overloaded. All trucks are underrated. I have to install air bags but other than that the truck pulls the camper just fine. I would not want to go through big hills though.

mstell, When you say E load range tires do you mean on your Truck or on your 5er? I wasn't planning on changing my tires.

I'll give you credit, it's a gutsy move going with the 3.5 liter V6 Ecoboost with a 3.31 rear end when you plan on towing over 8000 pounds. Starting from an uphill red light you're going to need all 420 pounds of torque from that engine with the 3.31 rear end. I hope this doesn't turn out to be a costly mistake for you. Good luck.

I have been following this thread, and feel the need to put in my $02.

Adding airbags to a 1/2 ton truck does not increase the payload, or the GAWR......it is still a 1/2 ton truck. A 5th wheel trailer is going to exceed the GVWR, and probably rear GAWR.

The listed payload capacity is misleading. On my truck the title lists 5236 lb. empty weight, with a GVWR of 7200 lbs., giving me a payload of 1964 lbs......don't believe it. I have weighed my F150 with me in it, 3/4 tank of gas, less than 100 lbs. of personal gear, and TracRac rails only, and I am right at 6000 lbs. That gives me an actual payload of 1200 lbs.....below the listed dry weight of the 5th wheeler in question........and that is empty weight. What happens when you add a 100 lb. hitch, the wife, kids, and other camping supplies, plus the added weight of the hitch when the 5th wheel is loaded for camping. The total is going to be well over the GVWR of the F150.

IMHO, most 5th wheels should be towed by a truck that has a full floating rear axle, ie a 3/4 or 1 ton truck. To put that kinda weight on a semi-floating axle found on 1/2 ton trucks is going to cause premature axle failure.

Put this question out there on RV.net and see what kind of answers are given......I betcha those will not be near as mild as the 1s given here.

Would you do it? I'm thinking I will. Just getting all the plans together.
Travis,
I may be misreading here but my F250 only has a GVWR of 15500. Are you sure about the 17100?

It appears to some of you posters, that the GVWR limit only applies to 1/2 trucks. If you have a 3/4 diesel, you've posted that it's okay to exceed the truck's GVWR, as long as you don't exceed the RAWR.

Interesting...

Dave

When I've looked at these trucks on Ford's site, you automatically get the 3.73 rear axle ratio when you select the max tow package. The towing rating would be a lot less at 11,300# with a 3.31 rear axle ratio.

I didn't see where the OPer stated the final drive ratio. If it is 3.31 gears, then maximum GVWR is 14,000 lbs. with an 8200 lb. tow capacity. The figures that the OPer gave match up with 3.73s.

Yes I will definitely have the 3.73 gears.
