Hitches are an important piece of equipment to have. With crosswinds, large trucks, and rough roads are a few reasons you will need the right hitch. Make sure you follow the rules of the road for using a hitch:
Will you have to install any holes in the body of your car to install a trailer hitch- If you do, make sure you remember to seal the holes when you remove hitch. If not, you may have deadly carbon monoxide entering your car. This can kill you. Besides that, you can get dirt and water in the car which will rust the car out prematurely.
Most bumpers are not capable of attaching a hitch to these days. And DO NOT attach a rental hitch or other bumper hitches to them. Use only a frame mounted hitch that does not attach to the bumper.
Safety chains should always be attached to the car and the trailer. Cross the safety chain under the tongue of the trailer so that the tongue will not drop to the road if it becomes separated from the hitch. (we have all seen at least one car/trailer on the side of the road do to this). Instructions about safety chains are provided by the manufacturer, follow them carefully.
Trailer brakes, does your trailer have it's own brakes- Contact your dealer to install and maintain them properly.
