Though I agree with planking it.. If you have an air bag system. you can try it. but two cautions.
one Make sure you do not exceed max pressure BANG you drop
Two How much lift you get (maximum) depnds on how much Stuff you have on board. You can easily lose several inches of ground clearance when you load 'er up.
Lose several inches of ground clearance from load? Don't they use leveling valves on MH? I don't know RVs, but on trucks and trailers load it, rig goes down, opens valve to increase pressure to raise it back up. (My last tractor, 62 lbs of air was 34,000 on the tandem. 95 lbs, was 45,000)
Also on trucks, the bag could stand full compressor pressure. Wear from abrasion most common cause of fail. I have seen some torn from over-extension, but never blowout from over inflation.
OP, I never did it but I'm sure you could plumb in a couple of solenoid valves, 1 to bypass the leveling valve, another to block the LV exhaust, and do what you want.
On my little trucks, where I did lawn deliveries, sometimes needed to jump curbs I carried couple of 2X8 and 4X4s. 1 each was 2 ft, the other 3 ft long. Each pair was tied together so I could lay 1 where I could see a tire would hit, and with the cord tight I knew the other tire would hit other board. Might do something like that with the blocks you put under leveling jacks...
