Is this the world’s longest truck? I don’t know, but it was the largest vehicle I have ever seen on the road. Normal highway trucks are 65 feet long. This one I think was over 180 feet. I saw this truck on the way to Fairbanks, AK. The road was a two-lane mountain road so it’s a wonder how this thing makes all of the turns. I was told the rear wheel assembly is steered by remote control from the truck cab. I wanted to see this in action, but also didn’t want to be behind it for eight hours. Lucky for me it was going south while I was going north.
