Actually this was one of the MAIN reasons I just purchased a Prolite Suite rather than a traditional tear drop.
Not quite 5' high but close,56" inside floor to ceiling. The bed is not my floor and the floor is not my bed.
Bed makes into a sofa during the day with lots of headroom, and we can stand well enough to dress and move around.
Ample storage under the bed. Can prepare some food inside when the weather is bad, also use the porta potti
simply by pulling over to the shoulder while travelling, set it out in a pop up shelter at night.
Three screened opening windows, screen door, plus fantastic fan should give lots of air flow.
Yet it still tucks in nicely behind my tow vehicle ( Subaru Crosstrek ) and weighs same or less than a 5x8 SS.
I think there is a lot of pluses to be had in this height range!
ps- I'm only 5'9" and my wife is 5'6" so this all works well for us. If you are much taller, forget about it!!!

under bed storage is substantial..
