Ugh, I just realized that the only hitch on eTrailer available for the hatchback is the Curt Class I, and I believe all of Curt's class I hitches require the use of their "stabilizing straps" for cantilevered loads such as bike racks. Does anyone here
actually use those stabilizing straps? I had a Curt class I on my Impreza and could NOT figure out a good way to route the straps over the hatchback spoiler, so ditched them right away. But perhaps that's partly what contributed to my unhappiness with the stability of the hitch/rack combo.
It's not listed on eTrailer, but Draw-Tite
does offer a Class I hitch that does NOT require the use of the straps:

It's a real bummer that Torklift does not offer an Eco Hitch version for the Fiesta. That's the model I had on the Impreza and it was considerably beefier than the Draw-Tite or Curt options.
