Auto level, at least most that I hear about and ours,seems to extend to almost max extension which brings our front wheels off the ground. Also for a fact, the level is close but not exact, you can raise or lower a bit and the level lights don’t change. We pulled into a campground in MS a couple of years ago and by pure odd luck we were in a row of Georgetown 378’s, 4 of use. Three units had their front wheels off the ground, l manual leveled and kept the wheels on the ground, and yes my auto level is calibrated. Visited the other unit owners and they auto leveled and noticed we had our wheels down. I purchased a level device from Camping World that has 4 lights, put in own the floor and level off of it. Works great and is very accurate. A bit pricey but excellent.
eBay link, I know Camping World has it.
