That truck is over 20 years old. Looks like it's in fantastic shape.  🤔 might not be up to the task of pulling that trailer with the multitude of axles in the background if it was loaded.

Good eye on spotting the Michigan centipede!!!!!  Load the wagon!! NO slop!!

Paul, the "Michigan Train" is a weird set up, axles are a duel tire axle and are 'fixed" but limited to 13K last I knew. GVW limited to 160k. None of the axles are a single wheel nor steerable. The idea is to reduce ground pressure by spreading over many axles.

I forget the man who came up with it, but the theory is more axles at a lower weight is easier on the road than traditional semi with axle weights at 17k-20K.

There are a bunch of rules you have to meet, I can't remember them all, it has been 30 years since I pulled under those rules, and only did one load. IIRC steer and drive wheel can carry more, but trailer and any jeep/stinger had to be at 13k.

They do "grone and pop" when they turn.

The theory may work going straight but turning it is hard on roads and equipment.

It is only legal in MI and some small parts of Ohio and Indiana, between the steel mills and the boarder with MI.

Yeah, there are a bunch a laws/truck configurations  that only apply in one or a few states that aren't legal nationwide.

When I hauled under MI rules, I was moving a crane that I would normally move on 5-6 axles and an overweight permit, but at the time Michigan's "Frost law" was in effect and they wouldn't issue any over-weight permits, I think I was 9 axle and well over 100' long but "legal" weight for a Mi train. I could get a over length permit. I don't remember what the GVW was when I made the move, but all the steel sure added to the weight to put all those axles under the load.

Funny part was: when I got to the refinery where the crane was going, I wanted to drop the jeep and stinger and just move on 5 axles. The guy leading me in, said he didn't want to wait for that (it was near quitting time) and anyway they had no problem getting OD loads where this was going! After snaking though the refinery roads in and around piping and tanks, he pointed to an opening in the racking and said "back it in there'!  Yeah, how many of you can back 3 sets of joints though a narrow opening in pipe racking? I got it done, but it would have been much quicker on 5 axles and one joint!
