What you propose will work, and probably 99% of the time you won't even notice the 30 amp current limit per leg. You could even parallel the two outlets, just not using the dryer while the RV is plugged in. It won't meet code, of course, but it will work...
Specifically, the only way this, with or without the switch, does not meet code is that 50A receptacles are not supposed to be installed on 30A circuits. Otherwise it's perfectly fine to have multiple receptacles on one circuit, generally speaking, and to switch them as deemed appropriate or necessary. It's no different than having more than one 15A receptacle on a single 15A circuit.
