PIts are wonderful to work in. They are also a huge liability as falling into one can be lethal. Building codes in many areas do not allow them.

I believe the shocks where stopping the droop of the axles, so the stress wasn't on the air bags -- From what I could see, they were not over-extended. This may not be true on older coaches -- but it appeared to be the case on my '95. Indeed, on some modestly sloping camp sites, the leveling jacks will bring the wheels completely off the ground, so BB must have engineered the suspension to allow for that.
