'05 W211 E320 CDI trailer hitch install

[ROLLGUY]

I purchased a Curt hitch for my CDI for around $140, including a 2" Euro Ball. The installation only took about 40 minutes total. The hitch bolts to the bumper shocks with U bolts, and also a tab on each side. The side holes needed to be drilled, and it was fairly easy to do. I drilled from the outside with a smaller drill, and finished the hole on the inside with a bit that worked for the 3/8 bolt. The wire bundle on the right needed to be moved out of the way, so it would not get damaged from the drill. I am planning to use it for towing a small trailer, which will never come close to the max rating of the hitch.
