Looking for Class C under 11' Exterior Ht. with A/C

For low height in a C, it usually means that the floor is built right down on the OEM mounting pucks rather than raised 6-10 inches about the chassis frame rails (i.e. no "basement") and often means no slideouts, because that basement gets created to make room for the mechanism of a "level floor" slide.

This makes Lazydaze and Bornfree the top candidates, since they don't do slides. Sometimes entry level Cs and rental models with no slides are built low, but not usually as low as Lazydaze.
