A fresh water tank you can carry under one arm: the Ronco RVB381 is a 34 gallon light-duty RV water tank with a shipping weight of 35 pounds. It is built for potable water service in motorhomes, campers, and trailers where a mid-size reserve keeps the taps running between fills.
Drinking water contact requires the right resin, and the RVB381 is molded from FDA-compliant natural polyethylene. The material's natural translucence means the tank shows its own level; no peering down the fill neck with a flashlight.
The RVB381 is rotationally molded as a single seamless piece by Ronco Plastics in Tustin, California. One Source Plastics carries it as an authorized Ronco Plastics dealer.
Standard fitting package
Choose the standard fitting package for $30 and we install these three fittings before the tank ships:

| Inlet | 1-1/4" female NPT | Top center |
| Outlet | 1/2" female NPT | Bottom center |
| Vent | 1/2" female NPT | Top corner |
Want to place the fittings yourself? Choose the blank tank: it ships with no fittings at no charge. Add the 90-2218 fitting kit ($55.75). It includes an access plate with six stainless steel screws, washers and nuts to mount it, a 1-1/2" NPT plug, two 1/2" NPT plugs, two 5/8" thru-hull fittings for supply and vent, and one 1-1/2" thru-hull fitting for fill.
