Basically it is open which tank I get. I donít have to match up to anything besides the frame and the rough area I have to work with, where the 1973 shower was. I guess if a choice of tanks will fit I would choose the larger capacity.
The first picture is a 1971 corner bath. The second is my toilet before I disassembled it. The third is, I believe, from a 1965
trailer and the arrangement I am trying to accomplish. I will build with the same methods as I used for my cedar strip canoe. Which is wood fiberglass epoxy composite. Or a wood core fiberglass pan. It is also the method Bart and Barbie did with there Tradewind for there shower pan. Nice Job there.
The last picture is the shower space I want to use. Has a 5" x 6" of dry rot to be repair as well as a worse one under the univolt from around the battery box allowing water in.
