The Ameri-Kart W1488 freshwater tank is discontinued, so the best replacement is to match the tank by dimensions, capacity, and fitting locations. Since your tank mounts below the trailer and experiences sun exposure, selecting an opaque, UV-resistant tank material can help prevent algae growth. Additionally, consider installing insulation or a protective cover to reduce sunlight exposure.

We offer several OEM-grade freshwater tanks suitable for horse trailers and RV living quarters. For example, the 25 Gallon RV Fresh Water Tank (27.75" x 17.75" x 12") by Elkhart Plastics is a high-quality option made in the USA. Another option is the 10 Gallon Alpha Fresh Water Tank (17" x 14" x 9.5"), made from FDA-approved polyethylene.

Since your tank is T-shaped with mounting flanges and specific fitting locations, exact matches may require minor modifications or custom fitting installation, which we do not provide. We recommend measuring your current tank's exact dimensions and fitting locations and using our Tank Finder Tool to identify the best fit. Installing fittings will need to be done by you or a professional installer.

To reduce algae and moss growth inside the tank, keep the tank shaded where possible and flush or sanitize it regularly. Using opaque tanks and protective covers under the trailer can significantly minimize sunlight exposure, which promotes algae formation.
