Could explain why generator runs okay when MH engine running.....the MH alternator feeding
Power to batteries keeps the voltage the generator "sees" above its shutdown limit.
I think I also remember some have addressed this problem by running a larger gauge wire
to the generator from the batteries so that less voltage drop occurs due to resistance.
"1. which set of batteries are powering the generator? - the house batteries or the chassis batteries. Since *most* RV spec'd gensets do not have an internal 12vdc supply (charger) they rely on clean 12VDC from the RV batteries being recharged from the converter. If the Generator sees less than 12.2 volts at it's connection it will shut down.
2. Poor ground to the 12volt system. I have had a few with bad or loose grounds powering the 12v side of the generator where they ground to the frame. In 1 case I ran a new ground from the batteries straight to the unit."
