We just bought the 363rb about 3 weeks ago. But it didn't have the auto leveling system on it. We have yet to stay in it. Hopefully this next week. So far we like it.
I know this is a late reply, but I was searching for any posts about the 363rb. We bought our 363rb in April, have camped various places from Florida to Pennsylvania and back (one very unlevel site in PA for 2 weeks), and have not had any issues with the auto leveling system.
