I have not tested the voltage with the engine running and the alternator further charging the batteries. I have always preferred to run the refrig. on inverter rather than propane while driving, for the obvious safety benefits. The question: If, with the engine running I am getting 110-120 volts via the inverter, but less with the engine off, as while fueling up, taking a break, etc., am I at risk or ruining the refrig. with the temporary use of the lower voltage? Any thoughts would be appreciated.

MSW, (modified sine wave), inverter output voltage can only be accurately measured with a true RMS, (root mean square), meter.
Meters other than a true RMS meter will often
show voltage that is lower than the true output voltage of the MSW inverters commonly used in most coaches.
I use one of these to measure the output of my MSW inverter:
