Not really a waste of money....wiring harnesses are available to add your own camera to the TC and still use the trucks OEM monitor for viewing. I would want that option since it gives you a hard wired back up camera when TC is on the truck
Had considered it by my understanding is it only comes on when the truck is put in reverse. By going after market I'll be able to use it while traveling down the road to keep an eye on the boat or other cargo trailer.
If it's not to late get the cargo camera. It a cam mounted in the third brake light. Makes loading a TC a breeze.
Already a breeze just by using my side mirrors. Can't get much easier to me and the wife will never load the TC by herself. Happy enough with her just sharing some of the driving once I get the auto.
