Even when the gray tank on our 2014 Sunseeker 3010DS is completely empty the level inside the motorhome shows at 1/3. We have been at our campsite for 3 days and the level is still 1/3. What could be the problem?
Sludge on the tank sidewall is enough to create an electrical current between the two probes.
Common issue with the tank probes. Dump ice in there, travel around.

Sorry, I was reading gray, thinking black. Could be a bad sensor, or if there is a metal band on the outside of the tank holding the tank it could be contacting one of the probes.
