DIY air leveling bags

It is interesting, but you can buy the airbags without all of the mounts. It seems like starting there would save at least part of the full cost of a set, but be a lot less work even though you would still build brackets.

Different type of bags. These are intended under the tires of a TT, to level before you engage the jacks, instead of stacking blocks. Our individual wheel loads on a truck camper are higher, so I'm not sure how well they would work.

As for the amount of lift, at 30 psi you would get 3000 pounds each bag. With dual wheels, that would give you 6000 lbs per side. I wouldn't be surprised if it would work to 50 psi, that would give you 10000 lbs per side. Typically, hose is proof tested to 4 times the rated pressure, so there is a safety factor there. Obviously, considerations for safety would need to be made. I doubt the stem would shoot out, if you used the backup washers as shown in the instruction post. If you really need that much lift, even consider a second layer of hose for reinforcement. But it would probably be prudent to make sure they were positioned toward a solid object.
