I just purchased a transparent trailer camera for my 2020 GMC Sierra 1500 for use with a 30' 5th wheel. 1) will I be able to calibrate the camera for transparent trailer view using the 5th wheel? 2) I would prefer to mount the camera up high on the trailer rather than the recommended placement in the middle of the trailer's backside. Would the camera still operate correctly or would I lose the ability of the camera to make my trailer transparent? 3). Is there a way to run the cable from the camera to the camera receptacle without the cable being noticeable? I'd just hate to have the cable so noticeable as to distract from the $70,000 niceness of my 5th wheel. Thanks for your input!
