I would say it was a Dutch lorry as they do have these extra long extenable trailers which they use a lot for the Windmills towers when transporting them to the building site. I would also agree it is a bit on the heavy side,
The double extender had a 15 foot extention on the centre beam making the trailer 100 foot long, the over hang at the back is 44 foot a total load length of 44metres or 144 foot
If you ever drive in the Seattle area, you may see a special trailer designed to transport wings for the 747 from one factory to another on public highways. This trailer was over 100’ long, and the wheels steered. There was a cab for a driver on the trailer, and a second driver steered the trailer axles around corners.
