I'm gonna install a hard wired camera. I've seen and chatted with a few wireless cam folks who really wish there was no interference etc. I think the big issue is where do you route the wires and do you drill another hole in the front of the cab for a quick disconnect? If you don't, the wiring will have to run outside and then you have to remember to connect and disconnect it for loading/unloading. Seems to me the cleanest install has a guy putting in another quick disconnect receptacle next to the one up front.
