You have your new motor home and are ready to roll. However, have you considered how much more difficult this beauty is going to be to drive? In particular, how do you cope with a blind-spot which is much larger than your sedan car causes?
All vehicles have blind spots. These are areas that the mirrors just do not cover between them. These are usually to the rear quarter. In a car these can hide another car. In a motor home, you might find several cars or a truck or two hidden away from view. Your high position and long vehicle exacerbate this problem.
One answer is simply to add an extension. The further from the side of your vehicle the mirror extends, the more you will see. However, because the mirror will all be at the same angle, you will still find yourself with a blind spot as well as a safety hazard as you battle to drive a wide load.
Some people prefer a different sort of additional mirror. These are usually frog-eyed or square-eyed mirrors. These fit on the top of the existing wing mirror and are shaped differently so that the mirror collects light from a different angle to the main mirror. This does mean that they often pick up vehicles not seen in the ordinary wing mirror. However, in altering the angle, they alter the perspective. Two reflections of the same vehicle will show different sizes different distances away. Which is correct? Perhaps you will work it out before you crash?
You could try a rear view camera. The trouble is that gives you another thing to look at inside the car instead of looking at the road and again may cause more danger than it averts.
The search for a good solution goes on.
