Another for the Softride hitch mount rack. Nice in that you can quickly (one move) pull the bikes straight rearward so that both the tailgate AND the upper hatch can swing open to clear handlebars, bar ends, etc. It even functions like a little bike stand for tuneups at camp with the aforementioned flat plate holding tools, oil and a drink or two. It also has the anti-wobble deal, an integrated cable lock that slips out of sight when not needed but is quickly deployed for a Taco Bell stop, and we've carried 6 bikes on it. These included a child's bike, a tag-a-long bike, two carbon road bikes, and two adult mtn bikes (long story). They also include a stout lock integrated into the anti-wobble mechanism. I drilled an extra hole in mine to clear the factory spare and this allows mine to sit back a few inches from the truck, but I think stock it will clear a huge bumper mounted spare.
The bonus is you can also get an attachment to carry several snowboards, or something like 4 pairs of skis - all in the wind shadow of the vehicle for MPG. These change back and forth in 30 seconds. I've been a roof rack maven for 20 years and can easily get them up there but there are just too many downsides with these great new hitch racks now available. This one's not cheap, but a paragon of good design now that I've had it for 2 years. All stout and overbuilt, and when I was shopping I found a picture of a guy carrying 8 mtn bikes on his down a rough dirt road and reporting minimal wobble. YMMV.
