Ok, you guys can decide whether you like this or not. At least it was a unique solution to a problem.
Ok, so I saw what appeared to be a mobile home frame heading down the freeway, at least 75 miles or so. Either I passed it, or it passed me, or one of us stopped for gas or at a rest area.
Anyway, I got to the auction yard, and was surprised to see the empty frame skeleton at the yard.
Then once I got loaded and was tying down, I saw this.
They were still tying down, so probably a couple more straps. It appears as if it was 4x4's across the frame and under the conex box.
40 footer, so about 8,000 lbs empty tare.
The trailer was something like a 30 foot mobile home frame, so it got the wheels at about the 2/3 point.
