Allrighty, it seems as though it's a big H frame,  welded to the frame rails. Receiver is 2.5inch with an adjustable hitch plate so you can mount your preferred hitch at your preferred height, although that's not really pertinent unless you like the idear to replicate for your use/needs.

Hopes this helps answer your questions. If not, feel free to ask me to send more pix
