I purchase a brand new Big Country 2950RK. The tanks have never had anything in them besides water for testing while I've owned this 5th wheel. With the tank drain valves open, assuming the tanks are draining completely, the holding tank level display shows that my holding tank and gray 1 and 2 tanks are 1/3 full all the time, sometimes one or two will show empty, but 98% of the time they are all at 1/3. Has anyone had this problem before and what was the solution to fixing it? Is it a wiring problem? Any information would be helpful and appreciated. Thanks again.
