So check this
out y'all (in my best Texas twang)....
I was just perusing the eBay classifieds, and found this truck. Amazing though it was, it wasn't until I got down to some pictures of pictures, showing what he was towing. It indeed looks like he mated an Airstream MH to an Airstream trailer, and the end result was a fifth wheel.
I wonder if anyone here has seen it in person, or knows what might have happened to it. It would sure be interesting to see some better shots of it.
