I personally had an "RV box" installed, which came with a 20 amp 120v
GFCI as well as a NEMA 14/50. This is the type of box you'll find on a
pole at RV parks, with a circuit breaker for each outlet (nice to have
right there) and the door has a large opening at the bottom so you can
plug things in and have the cords hanging out the bottom to get weather
protection while in use.
It does require a 70 amp circuit instead of a 50 amp circuit, but you
get the extra 120 volt outlet as a bonus for other use.

Assuming you don't plug/unplug the plug frequently, the connection on a NEMA

as hard wired (but if you exercise it frequently, it may eventually get lose,
leading to resistance and heat).
I agree. I've used 14-50s for decades for my EV chargers (and welder and
heater). The chargers stayed plugged in 90% of the time. I only unplugged it
when I needed to use the welder or heater. In 40+ years I never had to replace
one because it wore out.
Note: You can get receptacles that mount in a recess, so you can't get your
fingers on the pins when partially engaged.
