Yes, you can use a regular coffee maker in your RV, but there are a few things to keep in mind. First, you'll need to have an adapter to plug the coffee maker into your RV's power outlet. Second, the coffee maker will likely take up more space than a standard RV coffee maker. Third, you'll need to be careful not to overload your RV's electrical system. Finally, make sure to keep the coffee maker clean and well-maintained to avoid any problems.
