I've never seen one on any 78 Coachman up fitted coaches that I have worked
on. They were all transmode coaches when they left Pontiac. But, that being
said, they might have been ordered that way by Coachman. Actual transmode
coaches that did not end up as motor homes may have been fitted a number of
different ways. I know window and door placement varied a lot on transmode
as well as bathroom and tanks and generators. Roof air also. Just from
personal experience, yours might vary.
