Factory airbag suspension and overhead campers

Whats the weight in that camper?
2500 is probably the worst possible platform for a rigid in bed camper there is as the springs, coil or air, sit inboard the frame rails.
You should be looking at adding supplemental air bags (they are outboard of the factory bags). If you offroad, also use daystar cradles.
As to the bed lowering or ALT trailer height, all that's doing is lowering the rear. ALT is used for travel and lowers 1". Any other mode cancels at 8MPH.

2615 with all accessories.

So well over payload? How aggressive is the sag?

Can't use bed lowering mode while driving, only norm or alt. I would use alt height loaded, but on the 2500 there aren’t any big advantages to it.
I agree which the other comments, the Ram 2500 is not a good setup for a slide-in camper. I would upgrade the rear anti-sway bar and add aftermarket airbags. You can leave the air bags at min pressure when empty and let the auto-level do its thing, but loaded with the camper you can let them work together to decrease sway.
It has the auto-level suspension, so it won’t sag unless overloaded and the air suspension stops trying to level.

Higher than RAWR, but I’ve never seen a published number. Bags of that size are often good for 7,500lbs combined, but I don’t think the system will run them with enough air for that.
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!
2615lbs or around that!!!!!

You need some added bags or larger rear sway bar…

22K lbs is GCWR, and mostly marketing as it is not easy to obtain real world. It also has nothing to do with what you’re trying to do.
You have the worst HD truck for a big slide-in and need to supplement the auto-level with aftermarket airbags and a larger rear anti-sway bar.
The auto-level isn’t the issue, it’s the way Ram designed the coil/air spring rear suspension. It’s not a good design for high CG loads.

You were provided that info (use Alt if you want to lower the bed 1")
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.
Yes we plan on adding the helwig big wig rear sway bars on it! That should do the trick!
