> Do you have the brown cellulose glue-in insulation in the rear panel and under the rear clearance lights?


Did have, but removed it all when I pulled the caps. It was badly
deteriorated and mostly just dusty debris resting on the caps. Also had
some rotten foam (like black foam rubber, not the blown in stuff)
above the hallway panel, covered with a perforated cloth-like material.
That foam was also was crumbling to dust. There was a cotton batting
mat in the rear floor on the sloped metal section, like one
sometimes sees for firewall insulation. The main ceiling panel was
a cardboard type material, really quite tough and I wish I'd left it alone.
It was a single huge sheet that ran from the hallway panel to the front cap,
anchored by a bit of adhesive and a few screws with decorative plastic
rosettes. Think I might still have some of the rosettes if anybody needs them.
Anyway, the ceiling panel was different from later coaches in that it's textured
white surface was part of the cardboard and not glued-on fabric or plastic.
Even though it had gotten wet, it wasn't rotten or falling down, just a bit stained.
The plastic window trim corners on this coach had three screws each, not two
like the '75 corners. And of course it had real plywood cabinets, not particle
board. The hallway drawer fronts and table top were also made differently than
later coaches, by a more labor intensive but much lighter construction.
I'm sure there are other differences I've forgotten. I find the changes
throughout each model year fascinating.

Karen,

Thanks again... your info is the nearly the same as for my coach. The gaucho seating had a water tank across the rear -- no insulation on the sluminum slant. The same foam with perforated black plastic facing -- and it was lining the propane and generator compartment.
The front ceiling has no rosettes -- held up by the cabinets and a two piece metal joing strip at the front cap.

for those interested in Bill Bryant's photos of other 1973 production changes -- look here...
