This question already has an answer here:
Many years ago I saw a movie that featured a very cool vehicle which was referred to as "wasteland winnebago," I think. It vehicle didn't look like a winnebago at all. It looked more like a high-speed train or military airplane, with a flat pointy nose and a grey fuselage-shaped body, maybe 7-10 meters long. Its body had two articulated sections and its big rubber wheels were arranged in triangles like this.
The movie could easily have been made in the 70s or early 80s. (I wonder if it might have been an episode of a series; I have no recollection of its length.) I think it plays out after a nuclear war; at least, the world seems completely deserted save for a few outposts, and the world is full of threats like elephant-sized scorpions.
I saw in a R/C hobby magazine once that somebody had built a scale replica of the vehicle. That might have been in the very late 80s, probably RC Car Action.
I'd love to know what that movie was!
