Description

In Indiana, a charge of medium‑density polyethylene enters a rotational mold and emerges as a precise 100 gallon water tank—a horizontal square reservoir designed for everyday reliability. The natural, translucent wall lets operators verify fluid level instantly, while molded gallon and liter markings provide an exact read. Outdoors, UV‑stabilized poly resists fading and warping; in service, it won’t rust or corrode. A 5‑1/2" lid (5" opening) and easy‑tighten cap simplify refills, and a built‑in bulkhead fitting with a 3/4" NPT outlet makes fast work of draining, siphoning, or hose connection. Molded tie‑down channels accept saddle straps so this portable water tank rides securely as a truck bed water tank or trailer water tank, ready for farm chores, job sites, and water tank for car detailing setups. Rated for non‑flammable liquids to 140°F, it serves confidently as a potable water tank, a rugged water storage tank, or an RV water tank for extended trips. Made in the USA, it’s engineered for cleanability, durability, and dependable performance wherever you need compact capacity and square‑profile stability.

Never got around to using it for my intended purposes, but it held water and once I attached my ball valve it operated as it should. No leaks anywhere and it’s of great quality. It fit in the back of my Silveraldo perfectly too.

PIECE OF CRAP !!!!! I bought this thing to store water and after not even having it a year it’s started to leak at the seams in multiple spots. I figured for $400 it would be better quality but I guess I was wrong. I wouldn’t recommend buying this tank unless you want to replace it in 9 months. Total piece of crap. ... show more

Nice 100 gallon tank. No bulging at all when full. In the close up pic of the tank it has 105 gallons in it. The truck is slightly nose low so it would look more full if level. Very easy to fill and has a pressure relief valve in the cap. It has a female 3/4 inch NPT outlet, so I bought a plastic adapter male to male 3/4 NPT to 3/4 GHT (garden hose thread. I then could attach a Y adapter so I could attach two hoses. One hose will give me gravity fed cold water at the tailgate. And the other hose runs to the 12 volt pump in the truck bed that pumps water into the cargo trailer/RV conversion for the shower and kitchen sink. The Amazon source that offered free shipping ran out of stock. After a few days, I ordered the tank from another Amazon source that charged around $200 to Arizona for shipping. As soon as it shipped, the company with free shipping got them back in stock. So watch out you don’t end up paying for shipping if you don’t have to. I do recommend this tank. ... show more
