On purplewave.com, several straight trucks are on the auction block with photos of inside the cabs. I'm puzzled as to why so many of the them have the red trailer air supply valve on the dash? Here are five examples.
Why do many of these straight trucks have trailer brakes?

They might tow a trailer even if it's not a 5th Wheel ? Just my guess.
Oxbow Thanks this. -
Probably have a pintle with air brakes?
Oxbow Thanks this. -
The fourth picture shows a fifth wheel switch as well. I suspect it has been converted from a tractor.
skallagrime, RGT766 and Catmando Thank this. -
when I was doing expediting my straight trucks were converted tractors so had all the stuff a tractor would have.
RGT766 and VIDEODROME Thank this. -
I was obviously thinking they were converted but I was thrown off by the Freightliner flat bed. There is a pic of the axle numbers, supposedly factory printed on the body which indicate it was originally built with 4 axles.

Trucks are built by the manufacturer, and the body manufacturers put the bodies on. Trucks are built for multiple jobs, not specifically boxes. And yes, they could still pull trailers if equipped with pintle hooks.
