Got a 89 Winnie, 31rt Chieftain and just can't seem to find the power drain for the fresh water tank. Owner's manual says it is located by water hookup, but it isn't there. Anybody got any ideas as to where the drain is for the fresh water tank on this model? I don't really use the fresh water tank, but want to flush it out and make sure nothing is growing in it that doesn't belong there. Might be just missing.... :laugh:
