I have the
voyager camera. Love it. I have no problems with it working from rear of TT to front of Pickup. Dealer installed mine with wiring to hot wire of inside light so it isn't dependent on tail lights for power. I left TT at dealer and pulled away and it worked nearly 100 yards away.. the brick and steel framed showroom was then between me and the trailer, so it was no wonder it wouldn't pick up further.. oh yeah, this has microphone on camera, so if you have help, it is nice you can hear them without having to use radio/phone or yelling.
