Under eight inches tall. The 72W closes out the slice at 35 x 19 x 7.75 inches, putting 19 gallons into one of the thinnest profiles Ronco molds. This is the tank for the layer nobody sees: between a van floor and its plywood deck, beneath a berth flat, in the shallow tray over a trailer's axles. It is cataloged for RV and marine service alike because thin, wide voids are universal.
The Water / Waste Holding Tank series designation means the shell commits at order time. Fresh-water fittings: a potable tank in FDA-compliant polyethylene. Waste fittings: a 19 gallon gray tank that disappears under the shower pan feeding it. Same molding, your call.
It weighs 16 lb empty - solid for its size - and about 158 lb full at 8.34 lb per gallon of water, spread flat across nearly three feet: an easy load to secure well when it bears on the floor structure beneath. Thicker and narrower siblings are in the RV water tanks category, waste-dedicated geometry under RV holding tanks, and the marine placements at boat tanks.
