I very much appreciate the info from jimh425 and twodownzero, but azdryheat comments "Get the proper truck and keep the rest of us on the roads safe" was uncalled for. I was interested in getting information not commentary
Yeah... comments like that are completely uncalled for and are no help at all.
Your 2500 GM has a 6084 RAWR that will be carrying most if not all weight from a truck camper. The 6084 is the lessor of a tire/wheel or rear spring pack.
As cewillis says the truck will need some serious upgrades in the rear suspension from the ground up such as 19.5" tires and wheels.....air bags.....beefed rear spring pack or both. The 11.5" AAM axle won't have any issues with a 4k camper.
Run some numbers at ya' shows your trucks rear axle may weigh in the 2900-3000 lb range leaving it with around 3000 lb payload in the bed.
A 3500 SRW has a 7050 rawr and is good for around 3500-3700 lb payload in the bed.
GM 3500 DRW trucks have a 9375 rawr
Ram 3500 DRW has a 9750 rawr.
and Ford F350 DRW has a 9800-9900 ? rawr.
These trucks are good for 6k + in the bed payloads all depending on actual scaled axle weights.
