Levelling with wheels off ground

[Onyrlef]

I've parked two different coaches on a site that was uphill, i.e. the nose noticeably higher than the rear. The rear wheels come off the ground about 3-4 inches. This was at a friend's summer home that we visited for a week or so every summer, so not a one-time thing. One 22,000 lb coach had Power Gear levelers and the other (34,600 lbs) was Equalizer. The wheelbases were 19 ft and 23 ft, respectively. Mindful of the cautions about rolling, I always kept a foot on the brake pedal as the rear came up but never a sign of movement. Chocked the front wheels just to be sure, but again no indication the coach had shifted after a week or so. Both coaches had very capable jacks. I even wrote to Equalizer about the risk of bending and their response was basically "not gonna happen". I could tell that reply came from tech staff - no lawyer weasel-words anywhere!

Not sure what a foot on the brake pedal would have accomplished, that an applied parking brake ( power gear won't deploy w/o the parking brake engaged) and transmission in park wouldn't have, had the worst occurred ? The warnings I suspect are to keep someone on a steep grade from doing something stupid.

Foot on the service brake pedal engages both front and rear wheel brakes. Park/emergency brake only engages rear wheels brakes. Ditto for a transmission that has a mechanical PARK mechanism - it only affects the drive wheels.

Chocking the front wheels before raising the rear wheels off the ground might be a plan.
