The PROBLEM with door-mounted mirrors, when the vehicle has a hood, is that the driver is not able to see the area behind the mirror and along the side of the truck.  To overcome this problem safety conscious operators have accepted the premise that a supplementary mirror located on the front of the truck can add this area to the driver’s view.  Here the mountings found indicate that some operators place the spot mirror on the hood of the vehicle and some operators place it on the front fender.  Mounting hardware is usually a single arm for the hood-mount and a tripod for the fender mount.  The question of vibration should always be considered and we have concluded that the three legged tripod offers greater stability for the spot mirror and gets it far enough away from the body of the truck that its full maximum can be achieved. The hood-mounted mirror mainly shows the operator the body of the tractor.

The SOLUTION in this photo includes an 8 inch convex mirror mounted on the front fender with an M-C Spot mirror adjacent.  Again the factors of size to location and ease of viewing are apparent.
