I went with a Stromberg Carlson Bike Bunk (like Travelin Texans mentioned above) that mounts to the A-frame of my TT. I disassembled the cheap bike carrier I have and reversed the arms for the bikes so they sit close to the front of the TT and so my hatch will clear the bikes when everything is hooked up. They aren't secured in the photo, but sit well clear of the front of the TT when I have them strapped in. As a bonus I can see them in the rear view mirror as well as in my back up camera.
One caveat: Stromberg Carlson had their own QC issues and the first Bike Bunk I got was missing several critical welds. See my thread here:
