Norwesco 305 Gallon Pick Up Truck with Low Profile Design Without Fitting

The Norwesco 305 Gallon Pick Up Truck Tank (SKU N-44809) is a low-profile polyethylene tank built to ride in the bed of a pickup for mobile water transport. It holds 305 gallons, weighs 107 lbs empty, and stands just 30" tall on a 60" long by 58" wide footprint — low enough to clear cab height and keep the load's center of gravity down where it belongs. Molded in white FDA-approved polyethylene with an 8" lid, it carries a 1.5 specific gravity rating and a 120 F / 48 C maximum service temperature. This version ships without a fitting, so you locate and install the outlet and bulkhead hardware that match your pump and plumbing.

Will it work for your truck?

Sizing is the part people underestimate. Water alone in a full 305-gallon tank weighs about 2,544 lbs; add the 107 lb empty tank and a full water load puts roughly 2,651 lbs on the bed — the number you check against a half-ton versus three-quarter-ton payload rating. At the tank's full 1.5 specific gravity rating the contents can reach about 3,816 lbs, so heavier-than-water liquids close the payload gap fast. Before you load it, confirm your truck's payload and axle ratings against those figures and account for any rack or frame. The low-profile shape helps stability, but a half-full tank still lets water slosh, so plan for a secured, full-or-empty load. Run your numbers through the Tank Sizing Calculator and the Tank Sizing Guide to match gallons to your bed length and payload.

Fittings and setup

Because this SKU ships without a fitting, treat outlet selection as a first-step decision, not an afterthought. No factory outlet is molded into this version — you choose a bulkhead and outlet sized for your transfer pump and hose and install it where your plumbing runs. The 8" lid gives you fill and inspection access up top. If you want help matching a bulkhead and outlet to your pump before you order, call 866-418-1777 and we'll spec it with you. If this specialty tank feeds a fixed site rather than a truck, our guides on concrete pad sizing for above-ground polyethylene tanks and loadout pad engineering cover the civil side.

The mistake to avoid

The 1.5 specific gravity is a tank-material rating, not a green light to fill a 305-gallon vessel to the brim and drive. The real limit is almost always your truck's payload, not the tank's wall strength. Do the weight math first, mount the tank so it can't shift, and let the low profile work for you instead of overloading behind it.
