a larger motorhome is sometimes the hardest of RVs to easily Level, without any automatic leveling system, since it's unwieldy, and harder to maneuver onto 'blocks' or similar leveling devices.
I've found that you don't have to go by any 'level' and be 'exactly' level to be quite comfortable. If the hall bath door doesn't swing hard one way or the other, then you are probably 'level' enough. That's the main indicator we use, regardless of what our leveling panel 'tells' us. Level is as much of how you 'feel', as in an exact science.
Also, the coach doesn't care if it's level, only humans do!
