I don't have the lane changing warning with my new truck, however I do have a back up camera mounted in my tailgate handle.
I bought an aftermarket camera that is a plug and play, where the plug fits the GMC wiring harness under the box.
Aftermarket Camera When I load my camper there is a bit of farting around to do with removing that monster 18" tire to remove the stock GMC tailgate/ camera /wire / plug. And then plug in the after market camera, then load the tire back under the box. Then load the camper and feed the aftermarket camera up onto the ladder on the back of the camper.
Works great.
Soup.
