Hello, I have a 2014 Vengenance V396TH. We are fulltime RVing and in PA for the winter for some reason. My fresh water tank started to get frozen I think because it woulnt give any water only sputtered. Went to camping world in Harrisburg, PA and bought tank heater pad. I have a 106 gallon tank and they only had a 60 gallon pad. So I put it on and worked good for 1 night and now its back to sputtering and stopping and no water. Filled my tank so I know I have water in there. PLEASE help we need water and camping ground wont let us connect hose other than to fill tanks, then have to disconnect. I have even tried using hot water in the winterization tube of the pump to try and defrost things and not helping. I think it is the pick-up tube in the tank.
Any thought or ideas are very welcome.
When connected to city water everything works great only when off city water.
