Tow Vehicle
Until recently we used a 1993 Toyota Camry Sedan 2.0L with the electronic tow package as an option available with the vehicle. The Mazda 6 wagon pulls great. I have a 6 speed and just keep in 5th. Gas mileage in it is just a little better than what I get in the city... fantastic tow vehicle.
