Haha, I suppose I should have asked if the hole is a factory thing and what purpose does it serve.

Usually you see something like that on the back of a boat to let the water out..

Re: 66 GMC- what is this on the roof
My 66 with a Service Box had a hole there for one of those rotating flashing yellow lights. My 66 was an old County Truck.

I would think a roof mounted spotlight.

Re: 66 GMC- what is this on the roof
I would also assume the hole was created to mount some type of roof light. If exposed to rain, it also seems water might be prevented from entering the cab depending on what the plug looks like, but it appears a great deal of water would be allowed to leak in above the inner roof panel and rust out the windshield header and A posts.
