I'm also cringing a little bit to learn that the practice of misspelling words with a "K" is as old as the "Dumpster Kolector" from the 1940s.

I figured it was Dempster though I did not know they were originally loaded with arms like skips. Dempster also made the unique "Dinosaur" hoist for roll off containers which used a yoke slid by a hydraulic cylinder. https://www.classicrefusetrucks.com/albums/DE/DE05.html

I'd like to know who came up with the roll-off idea as they can also be used to create a modular truck system where you can swap bodies. I always though the ultimate do-all truck is a roll off hook-lift with a boom crane and trailer hook up.

This is a great HN submission btw!
