Thank you for the replies from Johnny M, Mitzi Agnew-Giles, Jon in AZ, and k corbin. Interesting that I got all 4 within minutes today since my post from august.
The progress has been slow because of fore mentioned medical issues . But the frame has been cleaned repaired and painted,new floors installed, the complete interior stripped and cleaned, remounted on the frame, and the top half painted.
I found the reason for the roof mount ac problem. the roof was strengthened with 3/8in Masonite glassed in but whoever did it only did three sides and did the forth side with corrugated cardboard and improperly sealed it, which means the cardboard got wet and rotten, giving no support on the one side and stinking to high heavens.
I changed my mind on the roof a/c and am putting a closet mounted 8k window unit in, and a fantastic fan in the roof, after feeling the draft in my neighbors 15 pod trailer.
We decided to remove the bathroom for now as we are mostly using parks. I am keeping the hardware for reinstall. I am building in a space in the freed up space for a cassette toilet for boondocking
I am now ready for mocking up new counter and closet wood work, and redoing the water and elec ports on the body, including an outside shower fixture for the beach trips.
thanks for asking
