At 19 lb of shell for 46 gallons of capacity, the RV22W is one of the most efficient moldings in Ronco's fresh water library - a tank you carry to the van under one arm, that then holds roughly 384 lb of water once plumbed and filled. The footprint is a tidy 36 x 22 inches at 14 inches tall, a block that sits naturally under a bed platform or bench.
Ronco's sheet lists it as the 22W L.D.: light-duty potable duty, natural FDA-compliant polyethylene, translucent wall for eyeball level checks. Fresh-line resin only - the gray/black side of the catalog at RV holding tanks is a different material for a different job.
Its nearest rivals are close enough to demand a tape measure: the 45-gallon RV47W at 36 x 23 x 13 inches trades an inch of height for an inch of width, while the RV33W carries the same 46 gallons flatter at 40.5 x 25.25 x 12 inches. The whole line is at RV water tanks.
