I purchased a DT 600/6000lb receiver online to install on my 03 Screw. Upon trying to install it, I found that the plate used to mount the trailer plug hits the factory safety chain ring on the left side. Rather than go through the mess of sending it back and getting a different receiver, I used a cutoff wheel to cut the welds and remove the plate. After performing minor surgery, it mounted effortlessly.

So, just an FYI that while it really is "no drilling required", you might need to do a little modification if you want to install this receiver. Hopefully this will keep future installers from being as frustrated as I was.
