They don't really print the fine print! All this adds up into the gross weight capacity rating (gwcr) of the vehicle. You can't load 1000 lbs in the truck, and then tow the max capacity rating. (No, I am not calling anyone's wife fat!). You have to stay at or under the tow rating and the gwcr. If you put 500 lbs. in the cab and bed of the truck, you essentially now have 500 less pounds you can put behind that hitch.

Tow capacities are calculated with an empty truck and only a driver. There is so much more to it than the sticker on the hitch.

Haven't found the GWCR mentioned anywhere yet.

Because for all but the newest trucks, everybody is way over. It might be on a door sticker, but it should definitely be in the owner's manual. Until recently MAX GCWR was 16k lbs. Lately the factories have been uping the numbers to 20-22+k. I'd expect you'll find the difference with the later Allisons (for the GMs). The early ones I think were still limited to 16-18k. And the 4L80/85 is limited to 16k.

Biggest issue is stoppping not pulling. Make sure trailer has electric over hydraulic brakes and in cab digital controller. Had a 382 w/525's,gen on a very heavy steel trailer (3,500#s Pulled it from Dana Pt to Colorado with a 09 Dodge 2500 Cummins, pulled fine. Vail pass and Eisenhower pass are both over 10,500 feet. Exhaust brake on the Dodge helped tremendously You dont need a dually for that much weight Air bags are great help

Nort - It is GCWR, not GWCR.

2011 F350 SRW is 23,500# GCWR and 14,000# conventional towing with weight distribution hitch.

2011 F350 DRW is 30,000# GCWR with 3.73 gears and 33,000 GCWR with 4.30 gears, towing capacity is 17,500 conventional with weight distribution hitch.

I have never seen a boat trailer with weight distributing equipment on it. The max weight on the truck towing is 8,500 (same for the dually too)......see page 29 on that PDF.

Nort. I put WD on my last boat trailer. It worked just fine. I have since upgraded trucks and trailer, (same boat) and do not use the WD setup any longer.

What truck?

I just towed my 382 to the keys from San Diego with a 2012 F-350 DRW 2wd crew cab. Plenty of power, comfy, satellite everything, ****ty hitch.....I reinforced the hitch on my 06 long ago to stop it from flexing. I did not have time to do it on my 12.
The hitch flexes just enough to keep jolting you in the back! I have a LD hitch with bars setup with this trailer. It works really good but made the ride worse due to the flex. I unhooked it in texas and went the rest of the way without. In the keys I dropped the hitch and took it to the local weld shop to add some gussets. Oh 10.5 MPG towing, 19.5 without trailer.

Sandiego, to the keys? DAMN THATS a HAUL.
