Quick towing question

Hello - Totally new to towing a 5th wheel and I have a quick question. I have a chance to buy a 2008 GMC 2500 HD with a 6.0 liter gas engine. It only has 36000 miles and is immaculate and was only used to tow a boat. I also have access to a 2007 Colorado 5th wheel. It's my father-in-law's. It's loaded weight with everything in it is about 9300 lbs. I'm willing to do all of the work to get all of the weights for the truck and use the calculators if necessary, but wanted to first ask if this truck would even be close to being able to pull this trailer before going to all of the work to get the weights for the truck. Any input is appreciated. Thanks.

You will need to get all the numbers to be on the safe side.
Including gear ratios on the truck. If it is equipped with 4:10 gears, I believe you'll be good . Different ratios have , different tow ratings.
A friend has towed both his 5ers with the 6l and 4:10. Montana to AZ, for many years. But I don't know his trailer weights.

EDIT: His original 5er was a 30' Gulf Steam , current is a 33' Cougar.

Thank you, sir. My Father-in-law is an experienced RV'er and is very thorough and can help me get good numbers. I just don't want to buy this truck if there's no chance that it can pull the RV.

Forgot that in my first post.
If the truck owner has the original owners manual , all the towing ratings will be in it , and the gear ratio info could be on an under hood equipment sticker, or inside the glove box. If need be a Chevy dealer can download a factory build sheet , if you provide the serial number.

Hope the truck suits your needs , hard to find a good low mileage unit.

The standard towing capacity of the 2008 Silverado 2500 ranged between 9,600 lbs. for a number of versions, and 10,400 lbs. on the high end. The actual tow rating depends on cab, 4x4 or 4x2, axle ratio, and how much stuff you haul in the truck other than hitch weight. Reduce the tow rating by the weight of any options in the truck, and anything in the truck except a skinny driver.

The tow rating is one of the two numbers you need. The tow rating tells you the max weight of any trailer you can pull without overheating anything in the drivetrain, and without being the slowpoke holding up traffic when climbing hills and mountain passes.

But the other number you must worry about is payload capacity for hitch weight. That's the one that usually bites you in the butt when dragging a 9,300 pound 5er with a 2500.

Given the numbers above, I suspect you'll be overloaded when on the road with a wet and loaded trailer and tow vehicle.

I had a '99.5 F-250 CrewCab 4x2. It was overloaded over the GVWR of the pickup with a small 5er that grossed 8,000 pounds when wet and loaded on the road.

So without knowing the exact wet and loaded weight, GVWR and GCWR of the truck, it's difficult to tell if you could pull a 9,300 pound 5er and haul the 1,700 pounds hitch weight without exceeding the GVWR of that pickup. But my guess is you'll be overloaded.

Thanks for all of the replies, fellas. It is much appreciated. I know I can trim some weight off of the 9300 on the trailer as my father in law has it loaded with lots of stuff that I could take out. I would mostly be using the trailer for my job to try to save on hotel costs and would be by myself. The towing calculators I've used so far (the calculator linked from this site as well as two others) have put the trailer under the max capability of the truck, but not within the 20% safety cushion that some people recommend. I have added about 300 pounds to the curb weight of the truck while using the calculators and tried to overestimate the other weights as far as passengers and other additional weights and used 300lbs as the hitch weight. The pin weight would be 2325 with the trailer at 9300 lbs and figuring 25% for pin weight (again, the trailer would not really be this heavy). The truck is a 2wd crew cab, regular bed with 373 gear ratio. Any further advise would be awesome just to supplement the calculators with human experience. Thanks again guys.

If you plan on towing with that truck a lot,...you're not gonna like it. Light to moderate towing, you'll be fine.

That's what I was thinking as long as the 9,300 is not the dry weight.
