how do you work under a MH with air bags?

Stacks of wood blocks can slip. The only reasonably safe way is to use big-truck size axle stands. BTW, Chris is correct. "XX-ton axle stands are rated to each support XX/2. I was looking at some Harbor Freight ones a while back and asked the question. They confirmed that each one could support half the rated weight.

Sorry that I wasn't more detailed. Blocks can slip easily. I made a set of 6 just for this purpose. I took 6x6 treated lumber and cut them in 11" lengths bolted 2 together side by side making them 11" x 11" square as a 6x6 isn't really 6". Then I bolted another pair of 6x6 blocks to the topof the first running across. Then another and another until high enough to fit under the mail frame with the wheels off the ground about 2". I also added a 24 x 24 piece of treated 3/4" plywood to the bottom as a base. bolted with 4 bolts.

I added a rope strap to each block set for easy handling and moving around. I space 3 block sets on each side of the coach evenly and centered on the frame. total of 6 block sets.

I used treated lumber so I can store them behind the garage when I'm not using them. They are specifically made for the motor home and there when I need them which is a couple of times a year.

I got this idea from a friend who built 8 sets to put under his coach in storage. He raises the coach using his leveling jacks and puts the block sets under the frame. Raises his jacks and his coach sits on top of the 8 block sets nicely. Tires barely touching the ground.
