As posters have noticed, people do a lot of unwise things with trailers. I have a friend who was towing his tandem axle car trailer with a one ton pickup... 2 5/16" ball, trailer brakes, good load binders, everything just as it should be... except he had a burned out license plate lamp. A state trooper who must have been in a bad mood pulled him over. My friend stupidly was smart with the trooper, who proceeded to pull out his rule book and go over the truck and trailer with his flashlight and a note pad. When all was done, he got a ticket for $1100 worth of infractions, starting with no fire extinguisher and going down the list. "Yes Sir, sorry Sir" is the lesson?
