We have six 8724s, two mounted on both kill trucks with two sitting on the shelf ready to go as replacements. The motors are rebuilt locally, about $67 each time, everything else we do ourselves. The youngest winch we bought two years ago, used, all of the others are more than 20 years old. The kill trucks work five days a week Jan-May, and six or seven days a week Jun-Dec. These winches are used DAILY. That is endurance.
