On the fresh water tank, sometimes they are inside under the bed, sometimes they are mounted under the camper.
To find the fresh water tank if it is not under the bed, go outside and look for a small white door (about 5" x 5") on the side of the camper. There is a key lock on it for key no. CH 751. When the door is open you will see a white plastic cap about 1 1/2" in dia. That is the gravity water fill spout and the hose goes directly to the fresh water tank. Follow the hose location and the white plastic tank will be about 2 to 3 feet from the fill spout. Inside or under the camper.
The gray water and the black water tanks are under the camper. Look for a 3" dump pipe under the camper and follow the plumbing. The black tank will be right under the toilet.
Do you know the model number?
Hope this helps
