The GCVWR on that truck is somewhere around 22k. So he's got to be in the neighborhood of 10,000 lbs overweight!

And about 2 foot too tall. Even if they deflated all the tractor tires, it would still be about 14 foot.

People haul over height all the time and you guys are giving him crap about it because it is a little trailer? I can see giving him crap about the truck being used or the fact that he probably does not have permits but not because of the trailer.
Yeah those are more than likely 7k axles under there and the tires are easily 3500 pound rated so the trailer is big enough. I would regularly put 20k on our trailer with no problems. -
Looking at that whole deal there just makes me feel uneasy. I feel they could have thought it through a little better.
HurstDominick253 Thanks this. -
I'm not saying it isn't more than a little sketchy...just that it might not be as "dangerous" as some are claiming.
northernhopper and wore out Thank this. -
Cant say I havent done some hairy things on trailers in my younger days. Ignorance is bliss though.

I figure that truck is about 20K and the trailer it is on is 5-6k. Those axles are 7k each: they are eight lug and no 17.5" tires so they cannot be 8K. Triple 7K is common for cheap trailers.
The truck is about 7K itself. 1ton or 3/4 ton doesn't matter to much for GM since their is a lot of crossover in parts between the two ratings. The one thing that doesn't change is the rear axle; all Duramaxes got the AAM 11.5 which is rated at 10K. Tires look bigger then stock 245/75r16 rated at 3k each. They look like 265/75r16 at 3.5k each.
So to figure out the capacity of the setup. You get 21k out of the trailer axles + 7k for the truck axle (2x3.5k tires) = 28k assuming little transfer to the front truck axle which is usually the case for these goosenecks.
At 28k - 6k for empty trailer - 3k (of empty truck on rear axle) = 19K of capacity, which is probably just under what that semi weighs.
The big problem is the rear axle of that truck. At 7k estimated capacity you have about 3k of that sucked up by the truck itself. If you maxed out the available capacity of the gooseneck at 4k you only have 14% of your load on that neck. It will pull like that but I would rather have 25%. You would need a dually for that.
You see guys all the time with tractors, backhoes, and dozers all on set up like this. A lot of that equipment now days comes in around 18k so this guy is not out of reason. He is just a little overweight, and way over that door sticker.Dominick253 Thanks this. -
That Peterbilt tractor is easily weighing around 32-34k pounds,depending on if there's fuel in it. You'd think they'd use a dually to pull all that to help spread the load.This has epic disaster written all over it.
