Installing car-mounted self-aligning tow bars can be a simple process, but it's important to do it correctly so that all towing is done safely. You'll first need to find a car-mounted self-aligning tow bar that's appropriate for the car you want to tow. You can find this out by checking with your RV dealer or looking for shops that sell towing equipment and towing accessories. They should be able to find the best tow bar for your vehicle.
You'll need to install a base plate or bracket, safety cables and brake light wiring kit to make sure your tow bar works safely. The base plate or bracket attaches the bar to the car. The safety cables provide extra attachment from the car to the RV, and the brake light wiring kit wires the car's brake lights to the RV's, so when the RV brakes, the car's brake light will light up, alerting vehicles behind you that the car is slowing down.
The brackets or base plates should be installed on the front of the car being towed. The specific place depends on what kind of car you have; the tow bar seller should be able to help you with that. The safety wires run from the bracket or base plate up to the hitch of the RV, and the brake light wiring kit is installed through the car's fuse box. All in all, installation can be done by one person in an afternoon, but if you're not very handy, you may want to let professionals take care of it.
Once you've got your car-mounted self-aligning tow bars installed, you're ready to tow. Pull up close behind your RV's hitch and attach it. Once the RV is under way, the self-aligning bars will lock into place, keeping the car the proper distance from the RV.
