Im looking for a dual back up camera kit. I will be putting 1 small camera on the truck bed or on the rear of the cab, to watch the hook ups for the 5th wheel hitch and the second camera will be going on the back of the trailer to watch whats going on, and keeping an eye on the second trailer since I will be doing double pulling. I heard about Tadi Brothers. Are they any good? Has anyone used them or are they just a bunch of overpriced cameras? Thanks in advance.
