I don’t know anything about semis, but every other year there’s a truck show/fundraiser for special Olympics in Joplin, MO. Close to 1000 trucks doing convoy, truck pull, concerts, etc. it’s quite the event to see everything from modern day trucks back to 1950s show trucks and any and everything in between.
