Trailer hitches on tow vehicles are the unsung heroes of RVing. They are used throughout the season and serve as the most integral component while hauling a trailer or fifth wheel.
Contrary to many claims by some manufacturers, the hitch and all of its components are not bulletproof and subject to rust and corrosion. They take the brunt of harsh weather and wet conditions, not to mention a ton of stress when towing heavy loads hundreds - if not thousands - of kilometres.
The good thing is they perform almost effortlessly when they are properly maintained and remain rust-free. But they can leave you - and your trailer - stopped cold at the side of the highway when they are not.
