Under seven inches tall and two feet long, the B270 slides 8 gallons into spaces most people write off as trim voids: 24 x 12.25 x 6.88 inches of low, flat molding for under a step, beneath a berth's foot, or across a storage bay ceiling gap. It is proof that usable water capacity hides in the geometry other tanks cannot reach.
Like the rest of the B-series it is a dual-role blank. Fresh-fitted, its food-grade polyethylene carries potable water - a camp sink's whole supply; waste-fitted, it is a shallow gray water pan for a shower or vanity that drains where no deep tank fits. Print the drawing below, mark your fitting locations along the long top face, and use the on-page fitting planner to spec the spin-weld or threaded fittings Ronco installs to your marks.
Thirteen pounds empty, about 67 lb full, and because a long shallow tank flexes if bridged, bed it flat over its full length. Molded in Tustin, California since 1974.
