How to Hook and Tow the Trailer?
First of all, before you buy a trailer, you need to install a tow bar for your front car. Each model has a corresponding tow bar. What is the drag bar? Many friends are not clear about this. The tow bar is actually a device that allows the front car to have a towing ability. It is actually replacing the rear anti-collision beam of the original car because the original rear anti-collision beam is very fragile, some use iron, and some use foam. All the carts must be equipped with this tow bar (except for some hard-core off-road vehicles with a tow bar). Many American cars are original with a tow bar.
First, pull the first line of insurance and swing the jack wheel clockwise to lower the hook. Until the RV completely buckled the ball in front of the car. Then go to the second insurance (aks rocker). The aks rocker intervenes when the rear car is out of control so that the RV does not swing. The third insurance: brake line. Only the car that hits the brakes will bring this brake line (if the previous two insurances fail, the vehicle will brake).
