Some manufacturers state they may void your warranty if you don't have their camper package and then carry a camper, assuming it's a company that offers such a package on the model you're considering. With Ford, depending on model, GVWR, and other options, a camper package may add stiffer front and/or rear springs, rear anti-roll bar (AKA anti-sway bar) etc.
Re 3/4 vs 1-ton, check your state DMV for GVWR and GCWR thresholds, as with some states you'll pay more for registration if you're over some certain amount and in other states you'll pay less. In some cases, different classes of driver's licensing also come into play. There's a fair justification charging higher fees as more weight causes more wear on roads and that's generally how it works, but sometimes industry lobbying reverses that for certain GVWR and people pay LESS going over some cutoff. All these issues are why with, for example, Ford you'll find 3/4-ton at 9900 or 10000 with exact same springs, and 1-ton de-rated to 10000 or at, say, the more typical 11400 or 11500. Wheel and tire selection also effects rating. A note on wheels and tires, with some smaller combos you'll have room for at least S-type tire chains or cables; with some larger ones they'll state you won't.
There's a lot of fine print in brochures and on DMV forms to review and in both cases staff may or may not be of help.
Re air bags, you may or may not need them and do note that at much more than the minimum inflation required to prevent collapse and damage, their more rapid increase in stiffness upon compression than a non-staged (without overloads) steel spring and could make for a bouncy ride. I'm not certain, but believe the factory system offered on Ram trucks begins compression when somewhat extended, whereas some aftermarket systems really only begin to provide support at about normal ride height. Such sudden transitions in spring rate would likely make for more bounce, so research and ask questions about system considered. I don't know about Firestone Ride-Rite on that issue, but a lot of people seem to like them. The factory Ram option supposedly helps a lot but it does look complicated. TorkLift upper StableLoads are another popular choice, but I personally have't used them yet.
