Engine battery and house battery questions.
My coach sat for about 8 weeks. Went to move it and the engine battery was dead, drained, kaput. House batteries were fine, they were replaced recently with new deep cells. Anyway I used the bypas...

We keep the house batteries charged by keeping our Class C continually plugged in with the house batteries switched into the system while the stock converter is powering the system. This doesn't harm the house batteries because we chose house batteries that are specified to be floated at the same voltage as the stock converter puts out.
While this is happening we keep the chassis battery charged by plugging a BatteryMINDer into a regular 120V RV receptacle and then plugging it's output cord into a regular 12V dash receptacle in the cab. The Ford's cab 12V receptacles are always hot and hence connected to the chassis battery all the time. This made it unnecessary to do any special extra wiring to keep the chassis battery taken care of whenever the RV is in storage and plugged in.
This approach makes it easy to take care of both RV battery systems if the RV is kept plugged in during storage and if the coach batteries are a good match to whatever charger/converter is built into the RV.
