One of two things. If the fields stay excited then the generator with the out-of-gas
engine will become a synchronous motor and motor the engine right along at 3600 RPM.
If the field de-excites then the out-of-gas one will stop turning and one of the
unit's breakers will trip from overload. In either case, since the other generator
can't handle the AC load by itself, it's breaker will trip. I'd wake up to a hot
truck cab, one generator stopped and one idling at no load.

I don't know which one would happen because I have them rigged up to take fuel from a
5 gallon outboard motor tank. Those two little generators would probably run a whole
day on 7 gallons of gas.
