I used auto-level just once - scared the daylights out of me. I don't know what the program was trying to do, but I didn't like how high it lifted. Our driveway is very close to being level, so I got a shop spirit level, placed in the bottom of the fridge and carefully operated the jacking system to get the rig level in both axes.
I then put two of the stick-on bubble levels where I can see tham from the level system control panel. One of them shows fore/aft and the other side-to-side. On most sites, I can get level within a minute, using the minimum of jack travel. If the site I'm assigned is too far out of level when I pull in, I ask for another one and move on if there aren't any others. A couple of places with pull-thru sites, I've gone around and pulled in the opposite way to make sure the back wheels stay on the ground.
The only place we go regularly where the front wheels are off the ground is the driveway of our daughter's house. We have to put blocks under the front jack pads and need a two-step bathroom stool to reach the bottom step of the entry steps!
