Mine is a rear kitchen and bath model with the couch/bed behind the driver's seat, and table and chairs behind the passenger seat.

For what it's worth, I also have a 1986 Travelmaster Savannah that suffered from leak issues. When I tore out the ceiling material I was able to see outside light through several pinholes in the aluminum roofing. These can be caused by corrosion, and they were not visible from above, and none of the inside leaks were at these locations. It's very difficult to determine the origin of a leak without tearing everything apart. I removed and reinstalled the vents using butyl tape (replaced ac with vent), and applied a liquid EPDM roof coating. So far, so good.
