Most of the drilling is simple and doesn't show. It's the 1in hole that seems to get people nervous. The landing block is slightly adjustable (L <-> R) so if the height is right, and the pilot hole is pretty close then you're good. I used primer and clear silicone caulk to seal the big hole up. My biggest issue is what to do about the holes in the tailgate and how to get a storage container where the cans are supposed to go.
