Wireless Reverse Camera Questions
Looking at a 2018 Jayco 43' 5er. Can either come with camera prep or a Furrion wireless unit. Prep location is center top of rear wall. Reports from Jayco owners on factory camera are mixed, report...

I have the Voyager and it works well on my 40ft 5th wheel. It does wag out once in a while traveling at highway speeds. I does better after I put the antenna straight up. I also have a Ford truck, but I doubt the Ford TPMS is the problem because its operating frequency is much lower than the Voyager frequency and is not at any harmonic. I believe the problem is the ground plane for the Voyager which varies when traveling. However the signal loss is not bad enough for me to improve the ground plane which would be a little tricky. The Voyager is suppose to have it own ground plane, but it is evidently too small. Increasing the voltage to the transmitter would be another option by running a separate wire for power. Presently I have it connected to the trailer marker lights which are not LED and the power at the Transmitter is less than 11vdc. Maybe changing them to LED would be helpful as well. But the problem is not bad enough for me to hassle with.
What are the freqs for the Ford TPMS system and the Voyager? Since the camera cuts out at higher speeds and the Ford TPMS kicks in at higher speeds its likely there is interference between the two. Get a spectrum analyzer if you are really curious.
The low voltage isn't the problem as mine does the same thing and my voltage is no where near that low. Also I have the repeater installed and it still does the same thing so it's not a signal strength issue either. You can add a counterpoise to the Voyager antennas if you want but it would be a waste if time.
Ford on the '17 Super Duties went with a WIRED system to avoid these issues. The TPMS sensors on the truck "talk" to the receiver mounted on your trailer and then the signal is fed via wire to the truck.The camera for the trailer is hard wired as well.
