Back in the day, cab-over-engine (COE) or "cabover" tractor designs served as the mainstay of the freight hauling industry. Yet they were eventually supplanted by the "West Coast" conventional "long nose" design as the longer wheelbase of conventional tractors allowed weight to be diffused more widely, thus lessening the impact of tractor-trailers on roadway surfaces. By the 1980s the cabover began to disappear at a rapid clip. Today, COEs only thrive in a few freight niches in the U.S., usually where space and/or a short wheelbase is at a premium.
