A 12 x 12 inch square section running 32 inches long: the RV27W is fresh water for the chase - the vertical or horizontal duct spaces in a coach where wiring and plumbing already live. Ronco's sheet lists it as "27 W L.D. (19 GAL) 32X12X12", and that square profile is what lets 19 gallons ride in a run most builders would write off as too tight for water storage.
L.D. is the potable spec: FDA-compliant natural polyethylene, translucent so the level reads through the wall. The blank is 17 lb; add about 158 lb of water at full. In a narrow vertical install, put your strap load path around the tank and into framing - a tall column of water has real leverage.
Downsized, the same narrow thinking gives you the RV23W with 11 gallons at 30.25 x 10 x 9 inches; slightly wider bays open up the RV39W, 20 gallons at 35 x 13 x 11 inches. Every footprint in the potable range is gathered in the RV water tanks category.
