Figured I would add this to this thread, it was asked in the other one and this is my two cents regarding what class it is.
Quoting alansupra94:
Wow, that looks amazing.
I guess my question now stands, what kind of class do you think that hitch is?
I would say class I, mainly because it's only using 4 of the available 8 mounting bolt holes. There are two more bolt holes on each side where the tow hooks would mount.
I would say that class II would be fine, if you use the additional 4 bolt holes that are underneath. The only reason I didn't, is because it would take a little more fabricating as the bolt holes are located perpendicular and higher up than the ones I used, making it a little more difficult to build. However I think down the road I might go ahead and do it, just to do it.
