I put a class 2 on a 240 once, really simple setup ultimately. Consists of a piece of quarter inch steel with six holes in it that sandwiches between the bumper and body hard points.

Then i used some random junk yard hitch, really only the receiver square, and welded it to the quarter inch plate so it popped out right under the bumper. Some gussets and a few other strength areas, and job done.

Unfortunately no pics of this arrangement, but it was pretty straightforward.
