I can appreciate it for what it is. It is a Hollywood movie fictional story prop. I think it looks great and really cool that they used a Jeep. Asking if it is real is like NASA criticizing the Star Trek Enterprise as a non functioning spaceship.
Old news. Some private owner did the work and tried getting it into the movie by bringing it down to the set. If you do a little digging you will find pics of the previous mods that included a stripper pole.
