It should be really easy to run the wiring with a cargo van that does not have seats and an interior. You could even install the backup camera with a wireless kit to transmit the image, so that you don't have to run all the wiring from the camera to the monitor. To the best of my recollection, backup cameras are sold at less than $20.
