That looks like a UniMog

I dreamed about this all night for some reason. In my dream however there were no windows because I must have remembered that first picture of the outside, which I understood was important for safety, so instead I converted most of the ceiling into a giant sunroof. This was smart (I thought) because nobody would know it wasn't a garbage truck unless you were parked next to a tall office building or hill.

Now of course I realize my glass ceiling would have turned it into a giant microwave, and there were a few small windows after all. All that mental effort for nothing!
