Saw one today, but it was coming at me and we passed at 100 MPH difference, so no time for a picture. One of those portable buildings on a loboy trailer. Kicker was that it had a porch attached, so wider than normal. To fit on the trailer, they had it centered, which meant the building portion was offset quite a bit, way over the side of the trailer. Centered by width, but I don't see how it could have been weight balanced. I wish I could have seen it better to see how they compensated for the weight being so far off center or how they had it tied down.
