That seam is where the back cab panel and roof panel pinch weld together. So that flange goes straight inward and is about 3/4" wide. Then there's the inner roof structure a little over 1" from the back cab panel. I've thought about doing this myself but not sure I've got the balls

Do you have a dome light inside? You can see what’s back there. It’s not scary. Measure twice, cut and drill once.

No dome light but I am planning to add one. I now have a headliner which I can use the cutout to locate the drill hole. I’m just not sure what’s behind it such as roof supporting sheet metal layer. There’s a groove on that outside surface and I’m unsure what’s behind it so I was hoping someone would share their experience. Thank you for the response Todd.

No dome light but I am planning to add one as well. Not concerned about the dome light since I now have a headliner which I can use the cutout to locate the drill hole. For the cargo light I’m just not sure what’s behind the panel such as roof supporting sheet metal layer. That cab back exterior panel has a significant groove between the roof line and slider window which I’m not sure if a metal support is behind it. I realize most of the surface will get covered up by the cargo light but I definitely don’t want to drill more holes than are needed since it could be a water entry point.
