At 7.75 inches tall, the RV72W is the flattest of Ronco's 20-gallon fresh water tanks - a 35 x 19 inch slab that slides beneath bed platforms and false floors where its taller siblings would push the deck up into living space. The maker sheet entry reads "72W L.D. (20 GAL) 35X19X7 3/4": light-duty, Ronco's potable designation.
Potable here is a material spec, not a marketing word - FDA-compliant natural polyethylene, translucent wall for direct level reading. The tank ships at 16 lb; filled, its roughly 167 lb spreads across the widest base in the 20-gallon trio, making it the gentlest of the three on floor structure per square inch.
The taller alternatives are the RV39W at 35 x 13 x 11 inches and the RV57W at 32 x 16.5 x 10 inches; one class down, the RV20W holds 19 gallons at 38 x 15.5 x 8.12 inches in a similar low format. The complete potable catalog is in the RV water tanks category.
