"franktr"......Be careful what you wish for. The side cameras can be a pain, especially if you tow a car. Obviously, the side camera comes on when you turn that turn signal on. This is great for looking down the side of your coach, but I never had an issue using my mirrors.
Here is where the problem comes, if you're towing. Once you turn your turn signal on, you loose your rear camera. I've always used my rear camera to make sure my toad has cleared the vehicle I'm passing. Now that my turn signal is on, I can no longer see the toad. If I turn the turn signal off, I get my rear camera back, but now no one knows I'm trying to change lanes. The side cameras just don't give a good enough perspective to tell if your toad has cleared the other vehicle. Mine are fish eyed, which makes it even worse.
When I first got my new coach, I though the side cameras would be handy for backing into tight campgrounds, by showing me the side of the coach that might be in danger. Well.....on my system, the cameras don't change when in reverse. So to use them while backing, I have to put the coach in Drive.
I think they're a neat idea, but just not worth what they offer. If it was easy to disconnect mine, I probably would, but it hasn't been a priority yet.
I know here are some systems that can show all three pictures at once or let you manually choose. That might be a better option. I'm just saying, do your homework before you spend the money.
