2017 Ford F-150 Questions

question is clearly stated

I have recently purchased a 2018 F-150 Lariat which has a camera in the tailgate. My truck has the 360 camera set up, park assist, trailer backing control etc. I'm having a shell built which will require me to remove the tailgate. The shell manufacturer says they can add a brake light camera on top of the shell to replace the tailgate camera. My problem is I've received conflicting and information from dealers, parts distributors and shell manufacturers as to how that will effect all the systems that rely on the tailgate camera. It seems to me that by raising the cameral several feet it will change the perspective and scale with relation to the other cameras. Looking at youtube I can see some evidence that the backing lines are partially generated at the camera itself.
So my question is, if I move and or replace the camera placing it higher on the truck will the systems compensate. if not do I have any options or am I just out of luck?

Thanks,
Robbie

WE'VE RE-CALIBRATED AND IT SAYS RE CALIBRATION COMPLETE, BUT STILL GIVES THE ALERT EVERY TIME YOU START IT UP AND NOW NEITHER THE COLLISION WARNING OR ADAPTIVE CRUISE OR REGULAR CRUISE CONTROL FOR THAT MATTER, WORKS. PLEASE HELP!! THANK YOU.

Front air vents work well --rear vents put out little air
