+1 to Tom & Barb's post. I have only used the auto mode twice and was scared both times by how high it pushed the coach.
My technique is to maneuver the coach on the pad to be as level as possible, then lower the jacks until they'e all just touching. I then level from that point on, using as little jack extension as possible.
The only place we regularly go where we get the front wheels off the ground is at our daughter's house. Their driveway is steep and we don't like to leave the tail end of the coach out into the street. We have wooden pads, made up from 4 x 4s with plywood top & bottom skins, under the front jacks. We need a bathroom step stool to reach the bottom step of the entry stair!
