Holding tank help for a 2005 Forest River Cedar Creek 30RLBS
I filled the fresh water tank to check the panel lights inside the trailer. It read empty for fresh water. I had filled the tank using a water hose. I didn't want the extra weight on the trailer just yet so I opened the drain valve underneath to empty the tank. I watched the water drain and I'm telling you there had to be only about gallons of water empty out. The trailer is supposed to have a 64 gallon fresh water tank. Am I missing another fill hole somewhere. I check everywhere but only found the city water connection.
Another question if you don't mind. The brochure states the trailer's Black and Gray water tanks capacity is 40/40/28. Are there three tanks? I can only find two places together where I would drain the black water tank and the gray water tank.
