Lost ground clearance will depend on vehicle and hitch manufacturer.
The Bodiak is a nice idea, but I wouldn't buy one. Have a hitch mounted winch? Then you can't use your tow hooks to attach to when using a snatch block.
Own a 3rd Gen Dodge? The tow hooks are not direct-frame mount. They are mounted to a bracket (also holding the front bumper in place) that is bolted to the frame. Shock load the hitch and you could misalign the front bumper/tow hooks/hitch, and have the possibility of the bumper contacting the front fenders.
Direct bolt on for me. I was going to fab up a hitch similar to the Bodiak (in terms of location, but mount behind the hooks then decided against it because of the not-direct-frame) but I ended up with a Curt (purchased used locally). It hung down below the plastic air dam. I cut it up and welded it so that it protrudes just below the front license plate mount and gaining me 2.5" of ground clearance.
