Note that some off road trailers have articulated rather than ball hitches, but not something you need to worry about, unless you want to do overlanding ( and I’m not sure any are for rent)
Some smaller trailers don’t even have brakes, but the heavier the trailer, the better idea trailer brakes are.
Some units have different ball sizes, and you rotate them so the correct size is pointing up.
