You know when your DW sends you a pic of this while shopping at the local grocery store she has an eye for TC's. Although this is not technically a TC very cool and unique rig.
Last year at the big Rollag, MN steam show, I was camped next to a rig that was just the opposite of that one. It was a very old tag along rig originally that had been mounted on a 5th wheel flatbed. The owner stated he had virtually ran the wheels/axles off it on a high speed run home to deal w/an emergency years ago.
Wish I had snapped some pictures. Other than the old run down look,it appeared to be a neat install.
