The receptacle is at the end of a run of #14 ga. running up, down and all around the garage
#14 wire is way to small to run 30amps.
#10 minimum.

I wasn't running 30 amps and I realize that would require #10. I was getting 98 volts with a vacuum cleaner that has a current draw of 12 amps. Even plugging into the garage recept. directly with the 30A shore power cord made no difference making it the overall length of the of #14 run inside the garage the cause (garage is about 1000 sq. ft with maybe 200' or more of overall #14).
My point is that anyone could have long runs of branch circuit wiring in their house/garage that could cause unanticipated excessive voltage drop.
