Do 2500HD's have upper overloads?
No, they don't.
I'd recommend Torklift Stableloads before Airbags.
The primary difference between the GM 2500 and 3500 diesel trucks is that the latter have an extra leaf pack. You can accomplish the same think by adding a set of SSA-13 SuperSprings to the truck. Unlike airbags the Supersprings need no adjustment and they cannot fail. The addition of more leaf springs keeps the truck handling as it was engineered to do by GM and the added support will improve the performance of your truck's shocks.
If only one of the two airbags fails your trip is over. Air bags are great for raising up the rear of the truck to better mate it with a trailer. Not the best approach for hauling a heavy camper. They also exaccerbate truck motion with a heavy load like a camper which is far more weight than most 5th wheel trailers will exert on the truck.
Before buying new tires to get more payload capacity I would recommend first finding out which 17" or 18" GM rims will fit your truck. The wider rims provide more options for tires and lots of kids buy a truck and then want flash and sell the stock rims and tires for 20 cents on the dollar. I have seen lots of good deals on Craiglist.
I did something similar as my new 2500HD truck came with tires rated at 3195@80 PSi and I sold these tires on Craigslist and they were replaced with Nitto tires rated at 3750@80 PSI - a gain in payload capacity of 1100 lbs. that cost me less than $500 in total for the upgrade.
