Max load capacity on our dodge states 22,000lbs. GVW is 10,000lbs. We are just looking for some advice for the factory air bag/auto leveling system!

What we're trying to help you understand is that anything you try to do with it is futile and won't improve the issues you're having. This may not be what you want to hear, but it's the God's honest truth from a very well informed group here. Honestly, we're trying to help you.
The design of the suspension on the 2500, with inboard coils, causes unsettling body roll with high center of gravity loads like that slide in camper. You're also possibly already nearing payload listed on the door sticker when running "wet" with the camper, all the gear and passengers. If you're pulling the UTV, add that hitch weight as well. If it's a diesel (you didn't say) you're well over payload.
The collective recommendation is if you want to improve the handling, you're going to need to either install supplemental air springs and a better rear sway bar, or trade it in for a leaf sprung 3500.
