Hey Rick, thanks for reaching out!
As long as you have the extra space for a larger water tank you can definitely use it. For example, the 15 Gallon Valterra RV Water Tank # R8030 measures 30" long x 8" wide x 16" tall overall so you'll want to measure under your Coachmen to make sure this will fit.

Hey Rick, did the 15-gallon Valterra water tank end up fitting under your Coachmen? Once you checked the space, it’d be great to hear what size worked best. Your update could make it easier for others upgrading their tanks.
