Thanks for the feedback. We are not stuck on entry level, just unit length (under 35). That is limiting to some manufactures. And then it was offered only on certain lines. For instance, we like the Keystone Alpine (has levelers) and also the Keystone Avalanche (no levelers available). We have looked pretty extensively so far, and will continue our search. Your comments have convinced me that auto leveling is definitely a must! If we find a particular unit that's our winner, we'll just call the manufacturer directly and see about auto leveling. It seems to be much less expensive through the mfg vs dealer add on.
