Squealing fan, buzzing, vibration felt through the floor and blinking 12VDC lights told me that another WFCO WF-9865 converter/charger is on it's way to the transfer station. I bit a higher dollar bullet and a Progressive Dynamics PD9260CV unit is winging its way towards our 5e. Abd they said a boat is a hole in the water that you shovel in money. An RV can't be too far behind
. I've had to replace a converter on every RV we have owned except the Titanium which had a Progressive Dynamics along with one of their inverters
