Hello fellow ML'ers!

Are there any slick hitch covers that look like they can from MB? To me, the OEM hitch looks kinda like an eye sore! I know about the normal slide in covers, but I am thinking more something that comes back to the bumper and integrates into the panel you need to remove! My panel looks like normal panel, but nicely notched out for the hitch!

Also, what is the story about towing and MB ML430? I understand they are rated to carry and haul X weight, but what is the real world experience? Tows great, tranny goes, blown motors or what else! Thanks in advance! BTW, I am new to my 2001 ML430 83K miles and I love it!
