It does one thing, but it does it well.
This is one of those things where it's debatable whether you can even call this a Jeep anymore. Pretty much all but the body has been replaced, and even the engine has been swapped for a high compression Chevy big block. But since that wouldn't be an especially productive debate, we're going to just sit back and be impressed by how well it gets through mud, demonstrating the value of a purpose-built vehicle for something like this.
Of course, the trade off is that it would probably be hell at the drive-through.
