Lowering the suspension
My coach is equipped with an Equalizer leveling system so HWH might be different.
On mine I can hit the auto level button (with engine running) and then immediately hit the power button to turn the system off. This causes the auto dump to be activated which dumps the airbags but prevents the jacks from deploying.
The bags won’t re-inflate until I power the leveling system back on and hit the “all retract” button.
