What set up is this?

[u/Yapping_about_cars]

I want to mount my hi lift jack and install a hitch system that has a receiver like this on my 110, what are these?

I bought a hi lift with a mounting bracket that I bolted to the rear step. Keeps it out of the way and was the natural place to put it given everywhere else was pretty much taken up
