I had to laugh at this "little big rig", which I noticed at IOTWReport.com. The initial video, in .GIF format, is silent.
Intrigued, I looked for more information, and found this video on YouTube. It's clearly of the same vehicle.
Apparently it was built by Walt Moss Trucking in Wisconsin. You can read more about the project here. Mr. Moss has produced several other highly modified vehicles using trucks and truck parts.
Fun stuff! Thanks to Mr. Moss for brightening up my day with his ingenuity.
