RV 42 Gallon Water Tank Replacement for 56x24.5x7 Dimensions

If the received tank exceeds the space available, keep it uninstalled while the item and measurements are reviewed. Send your order number, photos of the tank and any molded part number or label, and photos showing the length, width and height measurements. Include the available mounting clearance and outlet location. Compare the same measurement points, including the flange, sloped bottom and fittings; gallon capacity alone does not establish fit.

The catalog drawing for EPI 4451 / H1248005 shows a 56-inch length, 24½-inch width, a sloped bottom with a 7-inch overall side-view dimension, and a 3-inch outlet. This identifies the drawing to check, not the tank you received or an approved substitute. It is a holding-tank listing; the question's use of “water tank” does not establish freshwater suitability.

This general answer does not confirm a fulfillment error, a custom replacement, a completion or shipping date, a partial refund, or an in-person return arrangement. Under the current return policy, request a return first and, if accepted, follow the instructions and use the label issued for that return before mailing anything. Eligibility, shipping responsibility and any refund depend on the item and the review.
