Those vertical offset ones are great, because trucks are different and trailers are different.
I have what people call a “toy truck”, the receiver is ridiculously low, and one trailer we have is ridiculously high, so offset ball mount is a requirement.
There are different hitch ball sizes. I’ve got one lying around that has 3 ends.
The ones in the back need extensions to the ground to match their ridiculous lift kits, otherwise the trailer would tip ass backwards.
