I bought the 50 to 30 amp adapter just in case I get to a campground and the only site left was 50 amp only. Most of the campgrounds I have been in only had the 15/20 amp and the 30 amp receptacles but a few have also had a seperate power pole with 50 amp receptacle or a combination 15/20/30/50 amp setup.
