You did it! You found the perfect way to get away and relax with your family, camping in an RV rental. You found a great RV that has everything you need, except it could use just one more bed to comfortably sleep Grandma or the friend you told your kids they could bring along. Have no fear; there are some easy solutions to create a little more sleeping space in an RV!
This of course is the most obvious solution you may have already thought about. A cot can be lightweight, compact, easy to fold and store, and can fit in a tight space. They are a great option for camping trips and can be found at most outdoor stores.
