Waste water
We installed it in our bbq trailer. It fit like a charm. We are using it for the drained water from the sink. The nozzle for emptying out was a perfect size to darin.

2 Years on a Small Travel Trailer, working great
Installed on a 2001 Palomino Stampede after the original 5 gallon tank cracked on the top. The original tank was under the toilet above the floor (Found out the hard way the tank was cracked, yuck). Purchased this tank and mounted it under the trailer (Next to the gray tank which was already under the trailer), been using it for 2+ years now and am very happy with the tank thus far. Camping is primarily in areas where the temperatures do not hit the freezing point, so don't have any view if there would be an issue.
