AKA, First the family I' m talking about has a vehicle inspection station. which don' t matter, Now the vehicles have a towing reciever on the front of the truck. Just like hooking up your trailer to the back of the vehicle the unit simple plugs into the reciever and they can put it on and off by sliding it in and out with a simple clevis pin operation. Just like them deer xcarry carts you see on the back of the suv' s.
