Why don't you want to leave it like that?
The value of having automatic levelers is you don't have to carry a Rick of wood with you.
Maybe 10,000,000 times a year an rv is parked with the front wheels off the ground.
As an added bonus to how yours is stabilizing:
Some here are worried about their tires sitting on the ground too long and are looking for a way to get them off the ground so as to not create (an imagined and long discredited) permanent flat spot.
When this happens with our Vegas, I sometimes switch to manual and lower the front a few inches. Doing that cuts down on the pointing and commenting by people passing by, but really doesn't make that much difference. It just doesn't look quite as weird.
Bad decisions make great stories!
I never allow the wheels of my RV to be off the ground on the leveling jacks. My owners manual says not to do it as well. I carry a bit of dunnage to go under the tires for the few sites that are not level.
Bev: If it is level with the front wheels off the ground, you can stack locking blocks (yellow or orange usually come in a bag of 10) or boards under the front tires and then stabilize. Blocking under tires is much easier than trying to support from the frame.
