Today I was filling the freshwater tank in our 2014 Road Warrior 30C. I connected the hose and moved the selector to the "Tank" setting. Turned the house hose bib on approximately 3/4 of a turn and went into the camper to monitor the "Fresh" tank level sensor. The sensor never went above empty about 30 minutes later water started running from the rear of the front steps. What could be the cause of this leak? My assumption is that the tank is getting full and overfilling causing this leak. This has happened once before while I filled it from the house hose.
