The 64W is the biggest square in the book: 86 gallons on a 39.25 x 39.25 inch footprint, 14.5 inches tall. It is a tank built like a foundation slab - symmetric, low, immense - for the dedicated tank bay of a large coach or the engineered plenum under a platform bed. When a build needs maximum water from a wide space rather than a long one, this is the ceiling of what a single molding will do.
Series: Water / Waste Holding Tank. With fresh-water fittings it is a potable tank in FDA-compliant polyethylene, holding more drinking water than many household water heaters. With waste fittings it is a holding tank of genuinely industrial patience. The 83 lb empty weight is thick-wall molding scaled to the span.
Now the number that governs everything: about 717 lb of water when full, at 8.34 lb per gallon. That is engineered-mounting territory - distributed bearing, through-bolts, frame. Its light-duty potable twin in the same footprint is the RV64W; every smaller step down is in the RV water tanks category and RV holding tanks.
