shore power vs generator

[Gardner Yeaw]

On my '78 FC the generator seems to feed only one phase of the
breaker panel. There is a double pole 30 amp breaker in the
generator compartment, a double pole 30 amp breaker below the main
panel, and double breaker on main panel labeled MAIN,

It seems to be divided so that you don't overload the generator,
but I would like my microwave and coffee maker to work while
boondocking, or just stopping for lunch. I have a 6.5 Onan, which
should handle most loads provided I don't run both AC units at the
same time.

I seem to be missing the 110-volt wiring schematic so I can't
follow it. The two 30 amp shore line connectors are no longer there,
just the 50 amp. The shore line is wired to feed both phases from a
single 30-amp circuit. I need to monitor my usage to prevent
tripping the shore breaker, so I am used to it.

Is it normal for the generator to be limited in this fashion?
