Driving with a Trailer
Towing a trailer requires experience.
Get familiar with handling and braking with the added trailer weight. The vehicle is now longer and not as responsive as the vehicle is by itself.
Check all trailer hitch parts and attachments, safety chains, electrical connectors, lamps, tires and mirror adjustments. If the trailer has electric brakes, start the vehicle and trailer moving and then apply the trailer brake controller by hand to be sure the brakes are working.
During the trip, check regularly to be sure that the load is secure, and the lamps and trailer brakes are working properly.
