Mexitruck (noun):

A road vehicle (usu. a pick-up truck in grave disrepair) over filled with junk and/or working equipment (ladders, lawnmowers, buckets) that has the passenger area crammed with more people (most often of mexican decent, hence the name) than the vehicle can safely accomodate. Almost always driven at a speed of 10 miles per hour LESS than the speed limit.
