I looked at that Sportsmobile website and saw this:
"Sportsmobile's new Penthouse "G" installed on a Ford RB 8,600 GVWR van and
a Sportsmobile Conversion measures 83" high. This will fit into most
garages."

My '85 Westy is 83-1/2" tall at the skylight, '83" at the luggage carrier.
I haven't been able to get it in any of several garages I've tried.  I
measured my sister's garage today and the opening is 83", but with the
garage door up, the door hangs down to 82", so I could not get in it.

My Westy is not level - front springs are a couple of inches higher than the
rear.  Anybody else have trouble finding a garage to fit into?
