The large 9-inch by 6-inch McKesh Extended Towing Mirror, which extends out to 20 inches from the driver's-side door, allows one to see much more of the area behind the vehicle and any trailing unit (e.g., implement, wagon, spray tank, camper). It mounts quickly on door or fender of any vehicle, fits firmly enough to minimize vibrations, and will not mar the vehicle's finish. Also available is an optional convex spotting mirror, which can be mounted beside the towing mirror.
