Not a quality product.
I really had high hopes for this product since it's US made. I was going to install it under the custom camper but it is very thin walled. I feel even repeated impacts from grains of sand will wear it out and create leaks in no time. The dimensions are also not the ones listed in description. Poor molding. Basically a substandard product. Oh and they make you PAY for shipping if you want to return it, which costs almost as much as the tank. Not recommended, look somewhere else.

Great size Tank. Using it in my Skoolie Bus build. Along with a house toilet from Lowe’s
Perfect size Black Tank for my bus build.
