Phillip,

When you say multi camera system, are you referring to the the type that Rick's link takes you to? These are typically called 360 view, bird view, surround view, etc. It will be interesting to see how Rick's install goes with his system. In the past, the calibration of these types of systems was very difficult and required specialized equipment. Look's like Rick's comes with the calibration targets and the software must be built in. The other issue with this type of set up is that you will always have some level of blind spots at the corners, especially on large vehicles. You don't really see this issue with cars because of the size. The software stitches the images together so the blind spots are not so noticeable but they are still there so you still have to be careful. 

The other option (and the one most widely used on motorhomes) is a 3 camera set up, with a back up camera and a Left and Right camera. Most motorhomes have the LH/RH cameras mounted in the side mirrors nowadays, but you can get them with mounts that will install in the side panel of your coach. Just about any display with multi camera functionality will have trigger features that will allow you to tie into your turn signal so that when you engage left or right, your display will show that image.

Good luck,
Tony
