GM Representative: Other than the obvious differences that the 3500 has a higher payload and towing rating than the 2500, I'll need a time to find out.

Me: I am aware of that. But is it due to anything other than the extra set of springs? Is there a different rear axle? different front suspension? different gearing in the Allison tranny?

GM Representative: I cannot find anything that mechanically distinguishes the 2500 from the similarly equipped 3500, other than the suspension.

You may need to look at both trucks to see this extra set of attached springs inside the rear wheels. That is the difference. Airbags should provide similar additional support for the additional pin weight payload. Other components are apparently the same on the GM HD trucks.
Airbags DO NOT provide additional support for the additional pin weight payload. Airbags help cushion the ride and level the truck. They DO NOT increase payload ratings.

Rule #1. The Chief is always right.
Rule #2. When in doubt, refer to rule #1.

I really wish people would stop talking about air bags. They do not add payload capacity or towing capacity, all they do is make it a smoother ride. Payload and air bags don't even belong in the same sentence. If anyone tells you "add air bags and you'll be fine", walk away from them because they are clueless.

IMO, the Montana family are in the 1 ton tow vehicles PERIOD!!!, If you don't have a 1 ton or don't want one, then I would consider another 5'er model. Montana's are heavy with a heavy pin weight. The new Montana's (from 16 to now at least) are out of the 2500/250 trucks right from the factory, with on average of a #2300 pin weight (dry).
