💡 Helpful Tip: If you have the same 39" x 16" footprint, consider the 40-gallon option for nearly double the capacity with just 8" more height. For tighter vertical spaces, the 21-gallon models are your best choice.
Superior Quality You Can Trust
Unlike cheaper alternatives, this rotational molded tank features seamless construction that eliminates joints and weak spots. The high-quality polyethylene material won't crack, fade, or deteriorate over time, ensuring your investment lasts for years. The stain-resistant surface stays cleaner longer, and the corrosion-proof design means you'll never deal with rusty water or tank failure.
Easy Installation & Compatibility
With standard 1.25" fill inlet and three 3/8" NPT connections, this tank integrates seamlessly with most RV, trailer, and marine plumbing systems. The compact 39" x 16" x 8" footprint fits in tight spaces while providing ample 21-gallon capacity for extended trips.
