Does anyone happen to know of anywhere around north Misouri where i might find used a Black/gray water holding tank for this 87 Honey i have. I need a small tank. The one that was on it was too deep and it was torn up when I caught it on some high ground. This one was 12inches deep. I need one no more then 6 or 8 inches deep . around 20in x 30in. for gray water.
