Eric -

Welcome back.

My (ok really my wifes) coach has exactly what you speak of - a generator emergency start switch that (momentarily) combines the house batteries to the chassis batteries, in case where the house batteries are dead & cant start the gen.

My coaches engine / alternator charges the house batteries going down the road....i know this because i installed 20 bucks worth of panel meters & i can see the house battery voltage INCREASE when the coach engine is running.

I carry a set of heavy jumper cables with me - if i ever needed a jump and the over ride switch / relay isn't working i can just use the jumper cables to manually combine the battery sets.

Im not sure you really have to do anything to get what you desire - its all there on my coach now (from the factory).

HOWEVER....because of a relay....the the generator only charges the HOUSE batteries when its running, not the coach batts too.

Panel meters...get ya some
