Ronco Plastics RV23W - 11 Gallon Plastic RV Water Tank (30.25" x 10.0" x 9.0")

Ten inches wide. The RV23W is Ronco's answer to the space between frame rails: an 11-gallon fresh water tank drawn out to 30.25 x 10 x 9 inches so it drops into chassis channels and narrow benches that no squarish tank will enter. On the maker's own sheet it reads simply "23 W L.D. (11 GAL)" - light-duty, and in Ronco's language that means the potable spec.

Light-duty here is a material call, not a durability complaint: FDA-compliant natural polyethylene, molded translucent so you can read the water level through the wall with a flashlight instead of trusting a sender. At 7 lb empty it is genuinely a one-hand install; filled it holds about 92 lb of water (water runs 8.34 lb per gallon), so strap it to structure, not to paneling.

If your bay is boxier, the RV16W carries 12 gallons in an 18 x 13 x 13 inch cube, and the RV14W puts 12 gallons in a 24 x 15.5 x 8.25 inch flat. The full spread of shapes is in the RV water tanks category, and the same moldings serve marine fresh systems - see boat tanks.
