A wired system runs a video cable from each camera to the monitor. The picture has no lag and can’t drop out, which matters most on a motorhome, a box truck or a truck and trailer that stay hitched together. The catch is the install: the cable has to run the length of the rig and through the hitch, so most kits ship with 33 to 66 ft cables. Four-camera wired kits are among the cheapest ways to get rear and side views at once.
