Wade, what is the GVWR listed on the sticker of your driver's side door ?? That should also list your front and rear axle maximum axle weights.

Edit: Looking back, I see where Dave asked the same question on the GVWR.....my bad.

Another question: Does the truck have a full floating rear axle ??

OK, From the drivers door....GVWR-7,200 lbs.....GAWR FRT-3,950 lbs...GAWR RR-4,200 lbs.

Man, this stuff can drive one nutty

Well, it's really not an HD in terms of payload...no more than any other 1/2 ton. You reallly need to weigh it ready to camp and find out what the maximum payload is by GVWR and by RAWR. Don't forget to add 200 lbs for a hitch.

I was thinking it was like the 1500HD made 2001 to ? that were built on a 2500 chassis with 8 lug wheels, load range E tires and a GVWR of around 8600 lbs.

Wade, that 7200 lb. GVWR is the same as my F150.....go figure. But, your rear axle has a 4200 lb. weight rating vs. my 3850 lb. rating....a pretty sizable gain. Don't know why in the world your GVWR would be that low.

You stated in an earlier post that GM listed your truck weighing 7000 lbs. empty. That can't be right, as that would only give you a 200 lb. payload capacity. I think your best bet would be to take your truck to some scales and get a baseline on your truck to see what kinda pin weight you can handle before you reach the 7200 lb. GVWR.

Gentlman, I am I don't understand where the 10,500 lbs towing rating comes from other the book with the equipment that is in it. For 2008 this truck is rated to tow more then the standard 1/2 ton, the next step up from mine would be a 3/4 ton to be able to tow 12,000 lbs. I will do as you suggest and have it weigh and see if I can get some answers from GM, even if I have to get a factory Rep to explain the real story.

I may put this all on hold until I get some answers, thanks for all of your input my head hurts

For 5th wheels what the truck can carry (pin weight) is always the limiting factor, not what it's rated to pull.

Let us know what you find out.

I did a little more researching. Chev made a 1500HD model from 2001 to 2007. They were made using a 1500 style body on a 2500 series frame. They were powered with the 6.0 L, had a GVWR of 8600 lbs, payload around 3100 lbs, FAWR/RAWR of 4410/6000 lbs, 8 lug wheel and E rated tires.

In 2008, the 6.0 L still was available as the VortecMax, but not on a 2500 series frame. The GVWR range from 7000 - 7400 lbs, RAWR around 4000 lbs depending on body style, 2WD/4WD, payload around 1900 lbs, P metric tires.

The max tow rating of 10500 lbs is due to the engine's power and rear axle ratio...it has nothing to do with payload. The payload capacity is a function frame design, suspension and rear axle.

Dave, I just check my book and the payload is 1,921 lbs, this the 2008 4x4, 6.0 with a 4:10 rear and the heavy duty 4 speed trans, this rating is with the"Max Trialing Pack" with I have.
So now what does this mean as far as the 5th wheel I am waiting, is it a go or not....

Best thing is to weigh the truck full of passengers, fuel, gear, hitch...factory payload numbers are useless as they're with a 150# driver and little or no options. Make sure that you position the truck so that you get separate front and rear axle weights.

The payload available for pin weight by GVWR will be the GVWR (7200) minus the actual loaded truck weight. The payload available for pin weight by RAWR will be the RAWR (?) minus the actual loaded rear axle weight. The payload by RAWR will usually be higher than by GVWR. Some would say that you shouldn't exceed the trucks GVWR, some will say you shouldn't exceed the RAWR and some will say these specs are meaningless.

From that you can compare it to the anticipated pin weight of the new camper. From the numbers you provided I'd expect the loaded camper weight to be around 9000 pounds. Normal pin weight is around 20% which would be 1800 lbs. This is speculation...your pin weight % may be less. Our camper is a rear kitchen layout and was/is 15% pinweight empty or loaded and tows fine.

Personally, I wouldn't want to exceed the truck's RAWR, but that's JMHO.

Dave is telling you true.
You are VERY close so weighing your truck loaded as you would camp is real important to discover what you can tow as a 5th wheel. Don't forget to add what your hitch will weigh.
