Ronco RV Holding Tanks

Forty-two gallons in a 46 x 18 x 13 inch package makes the Ronco Plastics B182 the big tank for long, shallow spaces - bilge runs, under-berth channels, the full length of an RV storage bay. It is...

Nearly five feet of tank, barely more than a foot wide: the B240 stretches 58 x 13.75 x 12 inches, one of the longest slender moldings in Ronco's marine book. That geometry is a gift to sailboats and...

Most 40 gallon tanks buy their capacity with length. The B252 buys it with height instead: 26.5 x 21.25 x 18 inches, a compact block that fits where the long slabs cannot - a deep cockpit locker, a...

Nine inches of height is the whole story of the B346. Its 38 gallons spread across a 37 x 28 inch footprint precisely so the tank can hide under a V-berth, beneath a dinette, or in the underfloor bay...

A perfect 32 x 32 inch square, nine and a quarter inches tall: the Ronco Plastics B383 is a 36 gallon pancake built for square hatches and center-bay floors where a rectangular tank wastes corners...

The B432 packs 40 gallons into a 28 x 23 x 16 inch block - the compact-footprint answer when your bay is short but has some height to work with. Where the long slim tanks in this series chase length,...

Black tanks live a harder life than gray ones - solids, chemicals, long intervals between dumps - and 42 gallons is the size where a black tank stops dictating your travel schedule. The 21H is one of...

At 33.25 x 24.5 x 15 inches and just 40 lb, the Ronco Plastics B507 is the rare 47 gallon tank that one person can carry into place. The mid-height format splits the difference between pancake tanks...

The Ronco Plastics B386 spreads 45 gallons across a 36 x 33 x 10 inch platform, a near-square shallow format that suits mid-cabin floors and RV basement compartments equally well. The B-series...

The B210 packs 50 gallons into a 33 x 27 x 14 inch block - a squat, broad-shouldered footprint that puts serious capacity under a berth or a dinette without demanding the long chase a low-profile...

The Ronco Plastics B376 puts 45 gallons into a 38 x 22 x 14 inch footprint, shorter and wider than the keel-run tanks of the same capacity. That proportion suits transverse mounting: across an RV...

The 98H is the heavy one. Where its 25 gallon siblings blank out around the mid-twenties of pounds, this molding weighs in near 40, and in rotomolding, extra weight is extra wall. Thicker sections...
