Important: When entering the length, include both the full length of your RV and towing vehicle. The length refers to the total site length.**For vehicle information, only include the tow vehicle, not the RV. For example, if you have a truck pulling a camper, only add the truck. If you have a motorhome towing a car, only add the car** This is to prevent you from being charged for 2 vehicles when you only have one.
