ANSWER: Hi, the easiest way to tell is by looking at the plug on your RV. Take a look at the pictures at the top of this page and it will soon become apparent whether your RV is 30 or 50 Amps.

Do most campgrounds have 30 amp or 50 amp?

While the vast majority of parks will have 20- and 30-amp receptacles, and many have 50 amp power as well, occasionally you will find one with only a 20, only a 30, or (rarely) only a 50 amp receptacle.
