Attaching a troubleshoot listing from Ventline who manufactures some of the Monitor Panels in RV's. They suggest a reading of empty all the time (even when the LP tank is known to contain fuel) may be as a result of a short to ground on the sensor wire from the LP tank. If you disconnected the LP sensor wire from the Monitor Panel end you should now read a full tank (if similar to Ventline product). If that monitor panel reading is working OK, then likely the trouble is either a grounded sensor wire (maybe chafing through wire insulation has shorted the wire to ground), or perhaps the LP tank sensor has failed to ground. You could then try to isolate the LP tank end (if that is even possible at your sensor) and determine if the sensor wire itself is grounded to chassis with a multimeter (ohmmeter). Never use the ohmmeter setting on live circuits though.
