These are great ideas! Thanks. Not wanting to use low end items so I’m buying all new. Ronco plastics in Ca can make any size/shape tank I need. I will be using a porcelain RV toilet and a full massage shower enclosure. This should keep the wife and kids comfortable and happy. I sold a 42’ diesel pusher not long ago so my wife will need some comfort.
