Agree with the other posts, and if I had a 30 amp I would be tempted to use an adapter with the fresher, cleaner 50 amp receptacles. HOWEVER, as others have said in the past, it is technically a violation of the Electrical Code, since the 30 amp cable is being fused at the panel for 50 amps and not 30. Once you get to your RV panel, the rest of your system is then protected by your 30 amp main breaker. So the only liability is the plug, shore power cable, RV outside cable receptacle if you have one, and the wiring that goes to your panel. The odds of a problem, however, are minimal. You won't damage anything unless there is a problem on the run to your panel, and if there is, the 50 amp breaker in the pedestal will generally cover it fine.
