I was thinking it would be cool to DIY a camera in the cargo light area. Would be nice to flip on a separate screen for to see your trailer load or even blind spot views! Anyone ever try routing any cable from the cargo light area down into the cab? I really don't want to screw up my headliner!! At a quick glance, everything in the back above the rear window looks really neat and sealed up!! I don't see any easy way to access it. I haven't looked underneath the cargo lamp area, but on a video it looked like it was wide open under the lens leading to the headliner!! Any thoughts would be appreciated!!
