We have a Saris Bones, I'd love a hitch rack but the Bones moves from car to car, no matter who in the extended family needs to carry a bike. Everything from small SUV (Escape & Forester) to sedan to subcompact.

If I'm loading myself, I usually tighten everything a couple times. I learned from my MIL to put an old sock on the pedal that is closest to the car. A foam block works well too, but when the foam block disappears I've always got an old sock to use.

We can reach the trunk area from the back seat in our family car, but have to remember to load the trailer into the trunk before attaching the rack.

The hitch rack is on the "someday" list. I wish now we'd had the hitch installed on the car when we bought it. Next time...
