This 2 camera system gives me a full view of the road behind me as well as providing a closeup look at my toad. The backup guide-lines let me drive my 33' Southwind backwards with a trailer without any problem whatsoever.....and I can easily switch between the full-road or close-up modes to check on my trailer/toad when going through dicey road conditions. Very easy to hook up.....wire your power supply line and plug in the rest.

I bought a two camera setup, works great! One camera on the 5th wheel hitch, and one on the rear of the trailer. The camera on the trailer is setup to be on all the time I am driving. It really helps for backing up, but it is even better on the road. You can see cars coming up on the trailer and see if they are going to pass.
