Is there a switch or "mode" I should place the generator in when I want to operate off-the-grid?
Thanks again for your input.

OK, time to do some wire tracing. I suspect you have a tripped 100 amp DC breaker that should be wired directly to the positive side of your house batteries. On the load side of that breaker will be the starting circuit for the generator and the cross-connect device to tie the house and chassis batteries together.
The breaker, when tripped, has a red or yellow flag popped out sideways. Push it back in to reset it.
The reason it works when the engine is running is because the alternator output has triggered the cross-connect relay and is supplying 12+ VDC to the generator's starting circuit.
The reason it doesn't work when using the emergency start switch is because the switch gets its activating voltage from the house side of the cross-connect relay, which, of course, is dead with the breaker tripped.
This is assuming everything is wired normally - it may not be with a used coach. Find and check that DC breaker!
