It doesn't matter right. It doesn't matter wrong.
It matters that he doesn't know and dint know how to prove.

For 50 amp, All he has to do is look at the RV cord and see that it's #6 copper 4 wire. And if he looks at the plug on the end he will know what receptical to provide. For 30 amp he will find #10 copper 3 wire he will know it is 30 amp. If he sees a round or U shaped plug in the middle should know it is 120 volts. If he was to see and L shaped plug in the middle he would know it was 240.

Or he will look at the service name plate on the side of the RV with the service requirements listed there.

120 volt 30 amp outlets are not at all that common.

You can not plug a 120 volt 3 wire RV cord into a 240 volt 3 wire dryer plug without using a hammer. You can miss wire a 120 volt RV outlet to 240 volt service. BUT both plugs/outlets have the voltage written on them. If that gets screwed up the electrician is stupid.
