The 6 Best truck camper Water Tanks (2023 reviews)

This is a Non-Pressurized water tank, you will need gravity feed water to go directly to the water tank. The two smaller fittings are open, while the two 1 1/2" fittings are threaded but sealed with a thin membrane that can be cut out. The tanks will need to be braced and sit on a flat surface. It works well no issues and also it is a closed tank with 2 openings.

These big tanks can benefit from some support on the sides but if you're going to mount in a trailer you have to support it anyway to keep it from moving around when you are traveling so no big deal either. It is designed for stock fresh water tank set-up using a fill dish. It is made in a warehouse clean each tank prior to use to remove any debris, scuffs or marking from the manufacturing process.

Best For air vent: Barker truck camper Water Tank

Next on the list, we've got yet another tank that manages to win our hearts. It's the barker truck camper water tank and it's widely considered as tank that has the most suitable features. For an RV Water tank, this unit is a little on the thin side, and the wall thickness allows a substantial bowing out when full. It can hold water, and if you have it connected to a pump of some kind to feed the pressure washer it should work with some clever connections,then again a baby pool and a sump pump would do the same thing. It comes with a filler hose and a vent line. It’s meant for fresh water only.

The tank is made of PVC. It is suitable for the air vent. It is used for water storage in a small cabin.

This tank is just a basic tank. It's designed to be upright like the high country 1/4 round or 1/2 round vertical tank. It comes with a tank empty, pour chlorine solution into the tank. The tank has both 1/2" and 1.5" female threaded holes at the top and bottom corners. The tank is strong enough, but all the plumbing holes would be on top of the tank. It must be mounted flat.

The 40 gallon tank is the perfect size. It means you can use the tank for either a fresh water tank or a gray water tank, and the material is approved for both.
