Looks to be a Class 3 receiver there. Looks also like it could be beefed up from the flanges near the receiver to the far ends with not too much trouble.
Wonder if it'd fit a 560SEL? with Euro Bumpers. Or I could change back for a tow rig.
Interesting. What does it mount too under the car(small mtg end? Diff Mtg?

Did it ride below the bumper or did he have to cut the bumper fascia?

I know 20 Questions.
