Dimensions of fresh water tank? Mine is missing. 87 toyota Damon escaper mini

[AmySheller]

Hi,
I purchased this RV, 88 Damon escaper mini, and the fresh water tank is missing. I had one from a dolphin, close to the same year, but it doesn't fit. It is rectangular, 21 gallon. With the height of it being 6 inches, I can't get it to fit. Previous owner changed interior seating area, so I'm not sure if that's the reason. Does anybody know dimensions on the escaper fresh water tank? It says in the manual it's a 25 gallon tank. Is it rectangular/flat or more of a box shape? Any help would be appreciated. Thanks!

Since you have a RV that has been changed I would measure the area I must use for the tank(you may have more than one possibility of location) then see what is available to fit. Keep in mind input and output areas and pump area.
