I've got a Kuat 2 bike carrier that converts to a 4 if my kids care coming with. It tilts down, but not far enough for me to open the tailgate. So, I bought a RIGD swing out and mounted the bike carrier on that. Not fast, not cheap, and generally stays in place for a while, but it met the needs I had at the time.
I use a Wilco Offroad swing away hitch and a Kuat NV 2.0 thats a decade old.
highly recommend the Wilco. Bombproof and retains second hitch under the swing out. Also angled up for approach angle. Id get the 1up rack over the Kuat though.
