Cool... I was running a 3406B back then, the other trucks were typically newer 3406's or Series 60. The transfer trailers being double jointed and heavy to the back, they liked to push kinks in the corners so we never really pushed it speedwise.
Followed a set of triples off that one night, the rear trailer brake drums were brighter red than his brake lights. He offered to try and straighten it up so I could pass, but I politely declined, explaining that I would prefer to be behind and above him if he lost what was left of his brakes. He made it down to the flat, taking everything from gravel to gravel in the corners, and pulled over to let things cool, one or more of the trailers was locked up solid. Said there was no fire and he was gonna pull the pin and bobtail into town, so I saluted and carried on. The things you see.
