    It varies, depending on the engine, gearing, and whether it is single or dual rear wheel.

    Hey guys, I'm new to the thread and am dragging up this old post to save on doubling threads. It's a shame that the guys posting the question didn't respond back with his truck specs as this would have been good information. I feel I've searched thoroughly and can't find the answer to my towing question so I'm hoping you guys can help me.

    I just aquired an 85 dually 3500 gmc with a 454, 4 speed granny transmission and either 4.11 or 4.56 gears. It has both a class 3 hitch assembly and a fifth wheel. I am wondering the towing capacity of the truck. Obviously the capacity of the class 3 is limited by the hitch capacity, but what about the fifth wheel? I don't have a brake control on the truck but plan to do so.

    Thanks for any help you can provide me...

    Here is what they say about older vehicles:

    There are probably other ways to get the ratings but this is the quickest way I know.

    Thanks for the website, the site looks great

    Does anyone have an 'free' advice if the specs aren't easy or free to come by?
