240v is correct for 50amp RV service, if installed with a double-pole 50amp main breaker, as the service is really TWO hot legs/wires of 120v service coming into your RV - your RVs breaker box will separate these into two 'sides' of power within your RV.
if the outlet he installed has the typical RV OUTLET you would normally plug into at an rv park or campground, changes are he's installed the right one and correctly.
