Recently installed the Jensen Voyager Wireless System. Works OK, doesn't like cold weather. Outside temps we in the low to mid 30s when we headed South and had more times with No-Signal than we did with Signal. Once we reached warmer climate it worked reasonablely well. When you have signal, the picture quality is excellent, mic and speaker are on the tinney side, but to be expected of a small condenser mic and speaker. We have a 35 Ft 5er and Extended Cab Chevy Dually and I think if you had a longer Rig, you would have problem with communications between the Camera and Monitor. Camera antenna is attached to the camera, but I have the remote antenna and may try installing that farther forward on the Rig and see if that helps improve the communications. It is a nice system when working, but may be on the pricey side, I think it is currently on Sale, but still 700 bucks.
