Yes, I thought so and really like using it much better. Some will nitpick about the 50amp breaker for protecting the smaller cord to the interior's main, but no different than using one of those dog bone 50/30amp conversion cords like the OP is talking about and pretty far fetched for it to ever cause a problem when you get right down to thinking about it clear through.
Just have to be sure and wire it right, so as not to supply 240vac to a 120vac coach.

This is a great idea and should be no risk at all. You will only draw 30 amps maximum anyway because your entire coach is protected by a 30 amp breaker so you are just fine. Your cord will suffer no ill effects at all. It's not as if 50 amps is pulsing through there and being limited by the breaker on your coach.

But please don't share your idea with too many folks. I have to use 50 amp on my coach and I don't want everyone wearing out our nice tight functioning outlets at the campgrounds.

Only thing is, it's a matter of proper procedure and with just #10awg wiring between the 50amp pedestal breaker (should be 30amp) and the rig's main 30amp breaker, it not properly protected. Now having said that, a direct short between these two points will trip the 50amp instantaneously and it's pretty far fetched to have a situation where there could be a steady overload above 30amps between these two points. Like I said, it's no different than using a 50/30 conversion cord and evidently UL approved, so.....
