If you pull your trailer 50 miles to a seasonal CG then tow it home after the season, the Tow Max might last you a few years. If you pull your trailer on lengthy trips, then there is a very good possibility they will fail at the worst possible time. Let your fingers do the looking on the 'net for prime examples of Tow Max in particular or their Chinese brothers failing with expensive consequences.
