I wonder about GCFI only outlets. No non-GCFI
If you run into a stink with apparatus that poses no danger to you or others but trips the GCFI how do you intend to handle it? Not long ago I helped a fellow who had a three prong plug coffeemaker (expensive) that refused to operate in a 5th wheel. Kitchen outlets were chained to the outlet in the bathroom. The appliance was 99% plastic for the consumer so contact was no risk.
If you intend to hard wire this into your rig I would assume that the hard wired circuit would not be fault protected.
