I was thinking the same thing haha
Cutting a hole in the roof of a truck is like cutting a hole in the bottom of a boat
After the first one, its no big deal…lol
My boat has like 8 already for various intakes etc
I must admit, that is a sweet ride, I would never be able to do that if it was mine.
Just curious, was this done for looks, sound or the pure craziness??!!
I dunno… All of the above!
I couldn’t do that! 
not even to my old pickup.
If what you need is made this place may have it they even let you input the dimensions you are looking for.

I’ve installed sunroofs in two vehicles. Very awkward cutting holes in painted metal.
