There's really no difference between an RV grill and a backyard grill--except for the fact that you need something small enough to carry with you on the road. Just like backyard chefs, RVers and campers can choose between charcoal, gas, electric, or pellet grills. Grills can be mounted to the side or bumper of your RV, or they can be freestanding or tabletop models for use around the campsite. They usually fold up for storage when not in use.
