Almost square: the RV36W's 23 x 21 inch footprint reads like a floor tile, 9 inches tall, holding 17 gallons of fresh water. Square-plan tanks are the efficient answer when you have a compartment rather than a channel - a storage bay corner, the base of a closet, the platform under a bed - because they waste the least clearance of any shape against square walls.
It carries Ronco's L.D. potable spec: FDA-compliant natural polyethylene, molded translucent so the water level is visible through the wall. Empty weight is a modest 13 lb; at full it holds about 142 lb, spread evenly over that broad base - one of the most stable load patterns in the fresh line, often needing nothing more than corner blocking and a single strap.
If your space is narrower than it is long, two siblings rearrange similar capacity: the RV27W runs 19 gallons at 32 x 12 x 12 inches and the RV57W holds 20 gallons at 32 x 16.5 x 10 inches. Compare all the geometries in the RV water tanks category.
