The look and feel of this tanks are consistent with the high quality we're used to from the rest of Classacustoms's lineup. This style of water tank must be vented allowing air to move in and out when filling and emptying the tank. It is designed for stock fresh water tank set-up using a fill dish. 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. It is great as backup water for dry camping.

The tank is very sturdy and the fittings work great. It can be used with a 1.5" gray fitting and fill dish.

Why We Like This:

  • Inputting through regular harden hose with mip-adapter
  • Creamy white in color so you can see waterline through tank
