Check to be sure your particular car can be towed with all four wheels on the ground, recommends Mark Polk, a writer for the Family Motor Coach Association website. Some vehicles will require modifications to the drive train or transmission to be towed. Often, automatic vehicles cannot be flat-towed without changes to the transmission, since they need to be in neutral.
Look into the towing speed or mileage restrictions of your vehicle. Your car's owner's manual should be able to provide you with specifics, Polk said.
Pay close attention to your car's warranty to be sure flat towing of the vehicle is allowed. Contact your vehicle's manufacturer on the proper way to flat tow it behind a bus or RV. Each vehicle will have different requirements.
Install a lube pump into the transmission if your car requires it for towing. The drive train, Polk said, needs to be lubricated if a car is rolling. But if the car's ignition is not on, lubrication is not taking place. By installing a lube pump, the needed lubrication is provided.
Purchase a tow bar specifically made for your bus or RV. Make sure the tow bar also is compatible with your car. Most tow bars are rated for vehicles from 3,500 to 5,000 pounds.
Install the base plate to the chassis of your car. The base plate is typically custom-made for your particular car.
Install the tow bar to your bus or RV.
Connect the tow bar to the custom-made base plate on your car.
Wire a tow lighting kit and attach to the towed vehicle. Often the lighting system is gathered into one plug that can be plugged into your car's four-way electrical harness. From time to time, a harness adapter will need to be added.
