I thought the truck was a Ran 1500 at first. Knowing it’s a Ram 2500 makes me even more pleased since it’s a casting I wanted. I’ll let the pictures do the talking :)
Also, I had no luck finding the full movie online. I really want to watch the full thing. I’ve only seen the famous chase scene. You would think at least a movie from 1968 would be on YouTube but nooooooooo.
