The 2W solves the most common tank problem there is: a bay that is long enough but not tall enough. At 37.5 x 19 x 12 inches it keeps 35 gallons under a foot of height, sliding beneath dinette seats and raised beds where the boxier 35 gallon moldings will not go. Same water, lower profile - that trade is the whole product.
As part of the Water / Waste Holding Tank series it is committed to nothing until you order it. Fresh-water fittings make it a potable tank in FDA-compliant polyethylene; waste fittings make it a 35 gallon gray or black tank. Fleet upfitters like this ambiguity: one part number in the shop covers both plumbing runs.
Nineteen pounds empty; about 292 lb full, with water at 8.34 lb per gallon - that is an adult-sized load resting on whatever you fasten it to, so fasten it to frame. The RV water tanks category holds the taller 35 gallon shapes if height is no object, and RV holding tanks the waste-dedicated equivalents. Marine versions of these hulls are under boat tanks.
