Figure about 4500lbs for the camper. It’s doable with your truck, suspension mods and good tires or 19.5s (all weight cop comments/concerns aside), EXCEPT for the coil spring rear.
I’ve not experienced but have heard from more than 1 person that a heavy, high CG load like a truck camper is a handful with coils.
If you’d said 3500srw or older model 2500 with leafs I’d be more optimistic about it.
Regarding air ride, you don’t want the 2500 air ride for that weight. They die right about 4000lbs. 3500 air bag assist would work though.
