Trailer maintenance for heavy hauling

https://web-wiki.win/index.php/Trailer_maintenance_for_heavy_hauling

Keeping a heavy-haul trailer roadworthy means constant attention to the fifth wheel, brakes, and suspension. Even a small air leak in the lines can strand you with a 50,000-pound load. I check hitch pins and tire treads before every trip, and grease the kingpin more often than the manual says. A busted spring or cracked frame is not just downtime; it is a safety disaster waiting to happen.
