Why a 10-50? Why not a 6-50 or even a 14-50? I kind like having an officially designated EGC. Yeah, I know a 10-50's neutral could electrically act as an EGC on a dedicated circuit (which this most certainly would be).
I'd rather have a locking connector, but a straight blade will do. I also want some kind of cutoff switch before the outlet. One of those 60A motor switches would satisfy me, but maybe a small 2 slot breaker panel with a 50A GFCI would be good.
Some cars have their inlet on the front and some cars hav their inlet on the side (where one might expect fuel input to be).
