The Summit's lower fascia has additional design elements that would require different spacing for the tow bar attachment points, hence, two versions. I can't speak to whether you have two individual pieces or one piece (both attached with a cross bar), but, I've run into the same thing with getting the Blue Ox for a 2015 Cherokee Trailhawk that we're signing the papers on this Friday. My research results in the same two pictures... My base plate has been ordered by the dealer, but, we won't know which version will show up. Personally, I would rather have the cross bar. I would imagine that it would be stiffer, but, both versions would require the same disassembly, on the Trailhawk, and I'm sure the engineering is more than adequate on both versions.
