Well personally for me it would need to be a NEMA approved for outdoor use box, right at the power post, anywhere within the trailer creates a potential area for fire!
The issue isn't normal draw, it is if there is a issue within the AC unit, and it shorts out, then your 10 gauge wire now needs to suport 50AMPS of power that is available from the circuit breaker in the Power Post.
This is why I love having a 50AMP service in our 5er, every thing I use is strong enough to protect the wiring and dog bones.
that issue comes up every time somebody talks about using a 30 amp cord (or 15/20) off a dogbone 50 amp outlet, that the cord is not protected if something happens in the RV but that issue is usually dismissed.
