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 dual-role design carries through: order potable fittings and the food-grade polyethylene shell is a fresh water tank; order waste fittings and it is a ten-inch-tall gray or black holding tank.
It ships at 45 lb, one pound per gallon of capacity, and holds about 375 lb of water when full at 8.34 lb per gallon. That broad, flat base spreads the load well.
No two installations plumb alike, so fittings are installed per order, spin-welded or threaded where you mark them. Print the drawing below, work out which faces your connections should enter, and use the fitting planner on this page to finish the spec. Ronco has molded made-to-order tanks in Tustin, California since 1974.
