Anyone who’s had to drive a car or truck with a trailer hitched to it knows that the whole affair is a colossal pain. They’re a menace to steer, especially when backing up or making sharp turns. The vehicle handles bizarre, and is susceptible to wind shears, other drivers on the road somehow don’t understand how to behave around you.
Hitching them is never easy at all, and no matter how hard you work at securing the hitch, it can feel like it’s just not secure enough, and it’s hard to trust someone not to steal the trailer, if it has anything remotely valuable in it. This is why hitch locks are so important. It’s an often-overlooked necessity.
