A floor plan that is good for you is important - BUT...
my FIRST consideration was the chassis, engine and structure of the unit. There are very few motorhomes that are built with a welded steel framework for the coach. The one in my signature is one of the few.
When you see the results of a MoHo going off of the road or in an accident, most coaches simply crush and come apart into little bits.
Think long and hard about your expected use and time on the road.
At 120K you can get a very good and reliable motorhome.
