Review: Great Tank, Great Seller - I own two of these tanks. The ports are in perfect locations and I like the multiple options available for connecting the tank up. These are sturdy, well-made units. I had a problem with one order, but the seller was easy to work with and got the issue correctly rather quickly. I highly recommend this tank and Class A Customs.
Review: These are the best tanks - I am a professional bus converter and i love these tanks. For the money, its hard to find a better tank and the baffles add extra strength where you need it most. These are my go-to whenever I can make them fit
