Phase gets thrown around a lot, but 120/240 residential service is single phase. There are not two separate phases. A house and the power mast at your RV site has 240V single phase power coming in.
There is a center tap ground on the secondary transformer that puts 120V on two separate legs which allows you to get 120v by utilizing only one leg. Thus, we get 240v by going line to line and 120v by going line to neutral which is the grounded center tap.
Both 120v legs are the same phase and the system is better referred to as split phase with two legs.
Here is some more in depth explanation for those that care:
