Ya know, I've read about similar amounts of rivets to be removed to get a unit off of the roof. Sealing the holes left by all those rivets is part of what encouraged me to keep my Bay Breeze
running instead of replacing it.
But, I had a chance to explore how these remarkable units were mounted in 1967
when my Overlander had a leak that HAD to be coming from the air conditioner.
While a plethora of bucked rivets are evident after the shroud is removed, it became obvious that those rivets do nothing more than hold the upper unit together. I.e. the rivets were bucked before the unit ever saw the Airstream.
My roof-top unit is affixed by four or five sheet metal screws running on the port & starboard sides, and three screws underneath the fan motor.
So, if I wanted to remove my roof-top unit, I would only need to remove 13 or so sheet metal screw AFTER the Freon & electrical lines were disconnected.
