I'm looking at purchasing a new fifth wheel and I am getting a wide array advice on how much trailer I can tow. According to my owners manual my truck has a fifth wheel trailer weight rating of 17900 pounds with a GCVWR of 24500. I've been looking around at a few RV dealers to see what is out there and some tell me the most I can pull is a 14000 pound fifth wheel and some suggest that a trailer with a GVWR of 18000 is okay because I will never load it that much. I thought I would throw this out to the group. Anybody pulling a fifth wheel with a 2015 Chevy 2500 HD Duramax crew cab short bed and if so, how much does your fifth wheel weigh?

There are many people with 2500HD fiver combinations out there. Have you considered the 2500's payload limitations? The 2500 has a GVWR limit. This includes the weight of the truck, the pin weight of the fiver, people, fuel, and whatever other gear you carry in the truck. Payload is usually the limiting factor for a 2500 TV not the weight of the fiver...

Towing is totally different from load carrying capacity. Which is what your avter if you want to haul a fiver. A fifer is going to place approx 20% of its total weight dire tly over the rear axle of your truck. Since you dont have a trailer yet, use 20% of a fivers GVWR as your number of choice. Go weight your truck loaded ready to travel plus 200 pounds for hitch and subtract that from the trucks GVWR. Payload minus your intended fivers pin weight. Thats what you need to know.

17,900 5th sound good until you figure out the rear axle can not handle 3580 pounds of pin weight, the hitch and other things in the bed.My trailer has a 16K GVWR and is just about at that, and I am almost maxing out my rear axle rated at 7K. Person that told you 14K is close to the mark. Given a 6200 pound rear axle capacity you will not be able to tow a 17,900 5th wheel. And you would be way over the 2500HD GVWR also. Many do not care about that number and only worry about RGAWR. However at 6200 you are in trouble city.Chris

Bags or timbrens will eliminate the weight carrying capacity of your truck vs an equivalent 3500, provided your wheels and tires are also rated the same. I think I'd personally limit a SRW truck to the 16k lb neighborhood although some tow more without issues. What you load in the trailer is certainly relevant as well. Most here assume you'll be at full gross weight but that's overly conservative for some. Just depends on how you load it up.

You need to weigh your truck with fuel, gear, passengers to get actual numbers. As most of the FW pin wt will be on your rear axle, you need to stay under RAWR, and max tire.A 14K actual loaded weight FW, would max out your 2500. Like mentioned, 20 percent would be 2800 lbs, plus 200 for hitch. After weighing rear axle do you have 3000 lbs left before going over RAWR? Jerry
