Customer Question

The 42 gallon RV water tank I received has incorrect dimensions (55.5x26.5x9 instead of 56x24.5x7), making it unusable for my build due to critical width constraints. The 30 gallon tank was labeled with dimensions, but the 42 gallon tank was not. How can this be resolved?

Expert Answer

The 42 gallon RV water tank you received does not meet the specified dimensions of 56x24.5x7 inches, which is critical for your RV build. We acknowledge this discrepancy and are arranging a replacement tank from the manufacturer built to your correct size. Since these tanks are custom made, there is a lead time, and the replacement is expected to be available around the week of January 12th, following the holiday closure. If you prefer, we can discuss alternative solutions including a partial refund should you decide to keep the current tank. You may also return the tank in person during your next visit to Elkhart. We appreciate your patience and are committed to resolving this promptly to fit your RV build requirements.
