  • Top quality
Style: Cube Size: 29 Gallon
Bought this for my vintage camping trailer. Dimensions were perfect for the space I had. Quality of the tank seems to be excellent. Seems strong and sturdy to me. All the pipe fittings on it accepted everything I used and no leaks whatsoever. One picture says it’s 29 gallons and another says it’s 31. I did some math and converted gallons to cubic feet and I believe it is actually is 31. Time will tell how well it holds up but I’m happy with my decision to purchase it. ... show more

  • GREAT TANK FOR FOOD TRUCK
Style: Cube Size: 5 Gallon
I need tanks for my food truck. I purchased 3 of these total all of different sizes for gray and fresh water. They are sturdy. The fit is great for small or compact areas. The have not leaked and are very easy to install based on your plumbing plans. Would recommend for a food truck or RV.

  • Factory stripped threads
Style: Cube Size: 5 Gallon
Both .5” fittings were stripped when it came to me. At this point I had to weld epoxy over them to keep them closed as I needed the tank and couldn’t wait. I’ve installed other similar tanks with no problems. The 1.5” threads were fine. Too bad I only needed the 1.5” ones and not the factory opened .5” :( ... show more
