The point of creating a patio when you are camping is to create a personalized space that offers extra room. No matter how large your RV might be, it is nice to be able to spend time outside without having to be in the sun. Once you place an awning on your RV, you are ready to create a customized patio space.
Start with a rug or mat that is designed for use out of doors. Then add some lights; something both functional and whimsical. With a shepherds hook, you can add a wind chime or weather vane. Add a little statue, a table, and some chairs, and you have a room that can be used whenever weather permits. You patio will be a reflection of your taste and style.
