12v DC system failing sporadically
I have a 1997 Tioga Montara (Ford E350 V10 engine). Nice rig, works well. I disconnected from shore power 110v, and suddenly the 12v DC battery systems would not work. Lights, fan, water pump, etc...

You have an intermittent open circuit. Get out your meter or test light next time you have no power. Start at the battery terminals to check voltage. Then move along to the stack of 12v fuses. At some point you should find 12v on one side of something and zero on the other. Tighten, adjust, clean, repair, replace that device or connection.
