"wny_pat"...... I find the side cameras to be a pain. I change lanes by watching my toad in the rear view camera. As soon as I see it clear the vehicle I want to pass, I come over. The side cameras on both my current and previous coach give you a distorted view of what's alongside you. In a 35' to 40' coach, trying to determine what's beside you, 40' away is impossible. I only turn on my turn signals, momentarily, to let someone know I'm coming over and then turn them off.
With that said, if you're installing them just to see if something is alongside you, they might be useful, but will still be tough to determine distances in a small camera. If you install the cameras, DO NOT integrate them into the turn signals, as you'll lose your rear camera ability to change lanes.
I won't disconnect systems already in place, but I could do without the side view cameras. Much clearer to look in the mirrors.
