If you connect them and it doesn't start, try holding down the boost start switch. This should add the chassis battery to try and start. I used to do this on my old class "A". The boost switch works both ways!
If that doesn't work, the problem is the starter solenoid in the generator. Also I my old coach, occasionally when the house power was low, the Bendix gear would stick in the flywheel and the starter couldn't overcome the load. All I did was try it a couple of times and it would come free. If that is the case, you will see a voltage drop when you try to start since the solenoid is working hard but to no avail.
Finally, on my 335DS, even if the generator is running, which then powers the converter, it will not charge the batteries unless the house batteries are connected. Kinda dumb!
