Abstract: Systems and methods for mounting an easily removable, external protective system on a vehicle such as an internal combustion vehicle such as a car, truck, SUV, etc. One function of the system is to allow the occupants to enter and exit the vehicle without removing the system. Certain embodiments of the invention will be discussed and illustrated principally as it applies to Land Rovers' Discovery SUV. However it can be applied to any of a variety of vehicles, or even other mobile units such as camper shells. The invention can be advantageous, for example, as it provides protection for the body of the vehicle from many impacts where it would normally be vulnerable.
