If you are not on pPerfectly flat ground and place all 4 tubes I n the frame , you will twist the bus equal to the amount of imperfection of the surface.
  Maybe consider one end at a time and twist it less  ,as the end still on air bags will compensate.

I'm a bit confused. If I can get under where I'm going with the airbags down, I don't need jacks correct?

Correct.  If you have safe room with air bags completely deflated, you are good to go.  This is often achieved by driving the wheels up on boards for extra clearance.

It's interesting how shops completely ignore this safety practice. For example, I had Motorhomes of Texas repair my bulkheads a couple of years ago. I was there for ten days. The guys working on the bulkheads were under that coach countless times for hours doing the repair. No blocks. Same at the welders. I've always had a fear of vehicles crushing me and usually go overboard but these guys - no prob.

Probably several explanations for this behavior.

Time is money.  Takes "too long" to put safety measures in place for that "Once in a 100 Year" accident.

Ignorance is bliss.

Young people assume they are immortal.

Us Old Farts know better.  If you have ever had a vehicle fall off a jack or jack stands while you were underneath, it will make you a Believer.

I have.

If you put a pit in, then you would want to install an escalator so you wouldn't have to walk up the steps.
Just Kidding, but good thought.

Here in Shaky town, you have to worry about getting out from under fast, even using safety stands if your wheels are on blocks also.

jbeem,
If you are only going to use one per corner, it is best that the ones in the rear be placed behind the drive axle, not in front of it. The reason for this is that a frame block placed in front of the rear axle will directly apply force to pull the bulkhead joint apart. As the coach pushes the front of the "H" frame down, the torque tubes (AKA trailing arms, control arms etc.) are pulling on the bulkhead joint through the shackles welded to the 3" X 3" X ¼" transverse angle iron to which the basement framing is attached by the 17 Rolok fasteners. Sort of like a teeter-totter, push down on one end and the other end goes up, If a significant number of these Rolok fasteners are compromised, the downward force on the front of the "H" frame could cause or increase separation in the bulkhead joint. Probably wouldn't hurt a healthy bulkhead joint, but could definitely destroy compromised bulkhead and make a needed repair that much more urgent and possibly more expensive to fix. Even if the bulkhead joint appears to be fine, I wouldn't subject to that kind of unnecessary stress. It gets tested in use enough through the use of the transmission retarder.

I also used 1/4 inch by 2 inch  by 11 and 1/2 inch square tubing and painted them yellow so they won't be forgotten.  You definitely do not want to drive around with those in.  I bought it from a metal supplier and they cut it for me too.  I only use 4, some use 8, and I put them on the inside frame (toward center of coach not on outer part after rear wheels or before front wheels.

I place mine close to each air bag.  I left mine at 12 inches I have about 1.5 inches after I raise mine.

Be on the lookout for air lines routed through the area.  I have one airline I could pinch of I do not check and make sure it is out of the way. Actually it would likely cut it in two.  On the rear drivers side on my coach.  One of these days I will reroute the line to make that imposable. Some coaches could have wires in that area also.
