Hate to pile on your bad news. BUT, IF the line is to a jack, LCI jacks are Power EXTEND and Power RETRACT. That means you have to run the Power unit to retract the jacks, which will mean more fluid loss and possibly lack of retraction on the 4 jacks. There should be in the unit a 1800 number Tiffin supplies for emergency road service in the first year. That sticker used to be on the drivers side front overhead. Not sure where Tiffin puts it now. There should also be that contac info in the large Tiffin owners manual packet. Doug
