The monster Truck bags are a great way to transport your vehicle. When you get done having fun in the dirt and mud you can just put it in the bag and not worry about your car, yourself or your house getting dirty until you can clean your truck. The inside being made of a pvc layer can be blown out with an air hose and wiped out with a damp cloth so it is clean for your next adventure.
