2006 Monaco Cayman 36 Fresh Water Tank Replacement | 26.4 Gallons

The dimensions identify a possible comparison tank, not a confirmed replacement for a 2006 Monaco Cayman 36. Matching a 50¾ × 22¾ × 5¾-inch envelope does not establish the original tank's shape, support arrangement, port locations or connection types.

ICON's current WT3855 reference gives those dimensions and a nominal 26-gallon capacity. It describes specifically placed fittings for certain Forest River applications and references Forest River part 3847. The manufacturer catalog distinguishes 14887, replacing Forest River 3847, from a separate WT3855 configuration, 16526. Neither reference establishes a Monaco application. The manufacturer illustration distinguishes the 5¾-inch body height from a 7⅜-inch overall dimension; its separate 1⅝-inch raised-feature callout is not a thread or hose-size specification. Check the full installed envelope, not only the body height.

The ERVP WT3855 listing currently has native SKU 14887, but its retained “26.4 gallons / tank only” wording differs from the manufacturer's current description. Do not treat that wording as proof of a blank tank without fittings. Compare the exact SKU and supplied drawing with the original tank's markings, fittings, mounting/support and usable installation clearance before ordering. The question does not identify a 1.625-inch turret; the earlier answer's connection and customization assumptions were not established.

Use the product page for current price and availability rather than the former copied price. The correct replacement, supplied fitting configuration and any approved modification remain unconfirmed for this Monaco. The earlier best-match and certification assurances were too broad; verify the exact supplied tank and applicable manufacturer documentation before purchase.
