I have a 2002 F250 Crew Cab 4x4 w/ the 7.3 all stock except leveling kit, F350 blocks and 34" tires. I'm looking to possibly purchase a 5th wheel toyhauler. It is around 36 ft. in length and I guess around 10,300 lbs dry weight and around 17,000 GVWR when loaded (toys, etc). I started to google what my truck's towing capacity is, and I read something that stated a 12,500 lb towing capacity. Is that correct? Once I read this I told the seller that I was concerned the trailer was too much for my truck, and he said that I should be fine. He said he tows it with his 2006 F250 w/ the 6.0 liter (which I know has more power than mine).
Anyway, is this too much trailer for my truck? Or should I have no problems with it? I'm a little worried about having the power to pull it up grades because my truck has never really impressed me with my previous trailers that weighed less.
Your truck is going to be illegal, but it'll get it done. Make sure that there's nothing wrong with the brakes on that trailer. At 17k lbs, your life is dependent on them in an emergency.
Your truck is the heaviest variant of our truck, and it should weigh 600-800 more than mine: a 2000 F250 XL 7.3 SC SB, 2WD, 6-Spd, with a tool box, a 5th wheel, and a full tank of diesel weighed 6,660 lbs w/o driver (curb weight).
I'm guessing you'd scale at least 7,200 lbs. A 5th wheel will put around 20% on its tongue, so around 3400 lbs at full weight. That puts your truck at 10,600 lbs on 4 tires, when it's GVWR is only 8,800 lbs. That said, an identical F350 has a GVWR of 9,900 lbs, and you're only a little above that.
Your total gross combine weight will be 17k + 7,200, or 24,200 lbs. That's a lot of weight, brother! Like I said, it'll pull it. You better just make sure it can stop, too. Good luck.
