Many have what we call the "Tone" hitch. It is much lower profile, slightly recessed design. It requires cutting the rear cladding. Here's a thread that shows a few types.
I just bought the hitch that Tom4Bren mentions in post #69. Getting it installed soon.

Curt makes a hitch, don't think it requires any drilling. Circ you just put one on didn't you?
