The 5 Best extra Water Tanks (2023 reviews)

The latest recpro extra water tank is an absolute beast in terms of its features, and rightfully takes the top spot with ease. It's made for fresh water. It has a great web site as well that is easier to navigate than some of their competitors. The big one with blue cap is the inlet for fresh water, the other 3 nipples are the vent, drain, and pump, so they will need to be removed. It's a tank so you can put whatever you'd like in it as long as you have the molded ports needed to make the connections.

The tank has no leaks and has nice fittings and is ready for install on a camper van. It does not have baffles. The tank has a great web site as well that is easier to navigate than some of their competitors.

Why We Like This:

Larger applications provide the ability to stay out longer
Sturdy plastic manufactured for long-life and to prevent contamination
Constructed to fit most rv, camper, food truck, and concession trailer water bays
Water supply for showers, kitchen, and sink

Best For home: classacustoms Fresh Water Tank

Buy on Amazon

The classacustoms fresh water tank should be able to handle its purpose and duties with ease. This tank holds 100 gallons. It is used for gray water only or fresh water only, but not both at the same time. It has reinforcement grooves if it is laid flat with shorter sides vertically. The triangular grooves in the sides help for stabilizing the tank which is a plus. It is a semi opaque plastic so it would be hard to see from the outside. It is recommended to use a fill dish or other gravity process. The ribs make it real easy to fasten them down.

The preset inlets and threads are amazing.

Why We Like This:

Stout tanks with great ribs for tie downs
New and hot release

Best For van: Class A Customs extra Water Tank

This is a “food-quality” tank so there shouldn’t be an aftertaste. It is used for a fresh water tank. It includes no pickup and it is great for a holding tank for an outhouse. It expands in a good way. The tank has a 1-1/2 inch female pipe threaded connection that is initially blocked. It is made in a warehouse to clean each tank prior to use to remove any debris, scuffs or marking from the manufacturing process.

The tank must be vented allowing air in and out when in use. It is intended for water (of various purpose) not gasoline.
