I am a new fifth wheel owner & I back up most of the time by myself. I thought maybe it would be a good idea to have a wireless camera & monitor in my truck for backing up & possibly when travelling ...
I have a 33' trailer and I bought a voyager wireless and it works great. I always have a strong signal.
and to wilber1 I was thinking of connecting my camera to my nav, but the voyager came with it's own monitor and I am glad I didn't add it to my nav because now I can see what's happening even while I am driving. It helps me to figure out where the cars are behind me.
