I think I remember seeing the 48' line marked inside of trailers before I started at Van Wyk for 15 years (they did not mark theirs) but I don't remember WTF for.Crazy. We moved from 48' trailers to 53' trailers and only load them up to the 48' line.
What was the point?
Is it for high mass, low bulk freight? Or stupid union rules? At Roadway we didn't have any 53 footers. Just pups and 48's.

It's for when you weigh out before you cube out. I haul some light stuff and it's loaded to the ceiling and the doors but the heavy stuff like laundry detergent you can't load past the lineI think I remember seeing the 48' line marked inside of trailers before I started at Van Wyk for 15 years (they did not mark theirs) but I don't remember WTF for.

I guess I forgot all that shit.
It's because a semi trailer, "semi" meaning it's wheels only carry some of the load, in this case roughly half, while the tow vehicle carries the other half of the weight.
Tongue weight on a bumper hitch trailer is negligible compared to its axle weight.
Anyway it's a bridge. Structurally it functions as a covered bridge, and the length of the span is chosen by the driver when he slides the tandems.
Longer spans can't support as much weight as shorter spans.
When they embiggened trailers from 48 to 53 feet it was just to add volume for light shit. They didn't re-engineer the portable covered bridge, they simply made them longer.
I guess the only reasons they make it possible to run the tandems all the way to the rear is for at the loading dock.
