Ronco Plastics RV47W - 45 Gallon Plastic RV Water Tank (36.0" x 23.0" x 13.0")

Of Ronco's five 45-gallon fresh water moldings, the RV47W is the one you can plan around from your armchair: 36 x 23 x 13 inches, published. A compact block - three feet by two, just over a foot tall - that fits under dinettes, bed platforms, and the framed compartments of most mid-size coaches without drama.

It carries the 47W L.D. designation on Ronco's sheet: light-duty potable, natural FDA-compliant polyethylene, wall translucent enough to read the water line with a flashlight. The shell itself is a 25 lb one-person lift; the water is the heavy part, roughly 375 lb at 8.34 lb per gallon when full, so build the mounting for the loaded case.

If the block is close but not right: one gallon up, the RV22W runs 36 x 22 x 14 inches and the RV33W spreads to 40.5 x 25.25 x 12 inches; at the same capacity, the RV58W and RV51W offer different outlines and builds. Everything is at RV water tanks.
