I heard in a video that the measurement from the front of the trailer to the center of the fifth wheel is 3ft. Is this always the case?

That's a good question that I was wondering myself because I'm building a simulator to help people learn the intricacies of backing and slow speed maneuvers.

It would make sense that the trailer manufacturers would standardize the distance from the front of the trailer to the kingpin so the companies that build trucks can design them around that number. But I'm not sure.

I'm positive the distance is the same on all trailers. I've never actually took the time to measure the actual distance but 3' sounds right. But its really a non-issue and never crossed my mind.

My company has some trailers that are designed for Intermodal transport that are 4ft from Kingpin to the front of the trailer, but we only have about a dozen of them out 3500 total.

They do exist though.


Transporting freight using two or more transportation modes. An example would be freight that is moved by truck from the shipper's dock to the rail yard, then placed on a train to the next rail yard, and finally returned to a truck for delivery to the receiving customer.

In trucking when you hear someone refer to an intermodal job they're normally talking about hauling shipping containers to and from the shipyards and railyards.
