Hello all, nicely done and informative!
I am soon to start our ground up build on a 170 chassi and was thinking about the shower/toilet area and a surround... It dawned on me to consider a custom made polypropylene surround with a 2 or 3" wall thickness ... this would double as a water tank!! 2 sided at 27/30 x3" x 60 is 9.5 gallons... why not??? 3 sides would be about 13.5 gal. or even have entire enclosure with door fabricated for even more holding cap.
Has anyone ever seen this ??
TNX in advance! DMncash
