If you are purchasing a brand new RV, or planning to rent one, you should definitely ask and find out whether your RV is 50A or 30A. While there are workarounds with adapters, it can put limits on what you can and can’t do. It is usually the much larger RVs that have 50A connection, so for the most part, if you are unsure, it is probably 30A.
If it is a 30A, which is usually the case, many RV parks have 30A and 50A connections, but some are now going with 20A and 50A, meaning you will need an adapter to plug into the 50A supply.
Do plug in your 30A RV to the 50A supply, you need an adapter that goes from 50A Male to 30A Female. I prefer the pigtail design rather than the straight adapter since it has more flexibility within your campsite.
Just keep one of these with your power cables and extension cords, so if you find yourself in a spot with only 50A power or with a 30A power connector that is unusable (this happens more often than you’d think, where it was damaged or installed incorrectly). This one also has handles on it to make it a bit easier when trying to unplug.

Depending on how often you use your RV, you will probably find you are using it a few times a season. While some RV parks lend them, some will now only sell them, as guests would forget to return them. So it will be much cheaper to just bring your own, so you have it when needed.
If you don’t know what power amp your RV uses, there should be a sticker by where the power supply is that will tell you.
