Scamp advertises the gray water tank at 26 gallons, and the black water tank at 8 or 9 gallons (I can't find a reference at this time...). The fresh water is 12 gallons. Experience tells me that my 2000
Scamp 16's tanks are about this size.
What happens of the gray water tank overfills? It spills over via the vent tube under the trailer. What happens of the black water tank fills up? It spills over via the vent on the side of the trailer. (ask me how I know this
). There is no connection between the black and gray water tanks; in fact, there are two separate outlets, one for each tank.
There is no need for gauges, as the gray water is larger then fresh water by a factor of more than two. If you must know the level of the fresh water tank, simply shine a flashlight into the translucent tank. You can shine a flashlight through the walls of the black tank as well, but due to the heavier construction it is harder to see the level of the contents. Alternatively, you can simply look into the tank when you flush (
on the latter counts).
