I currently have the shell off a 1963
Bambi and sitting on cinder blocks, and the frame flipped over and preparing to rewrap a new belly pan. I have the original fiberglass potty/black tank/shower combo, shimmed up from the bottom so I can layout the below floor plumbing before I close in the frame with the new belly pan.
This is just a rough fit for purposes of routing the plumbing, but I can already see that the underside of the fiberglass pan is pretty uneven compared to the "laser" level plywood floor.
Weeks way from flipping the frame back over, dropping the shell back on, and really re-installing the fiberglass pan. But was wondering what will be the proper way to reinstall the fiberglass pan, and have it properly, evenly supported from underneath ?
