Pullrite Superglide or Demco Hijacker?

I have had both the Pullrite Superglide and the Reese Sidewinder, which doesn't appear to be on your list. Either will work well for you.

Since you're specifically asking about the Pullrite, it works great and is a fairly smooth ride. It's very heavy and a pain to remove. I'd probably consider one again, as it handles more predictably than the Sidewinder in certain situations. I've since moved to a long bed.

The benefit to the Sidewinder over the Superglide was that we could pack stuff behind the hitch because you use a standard fixed hitch that does not move in the bed of the truck. You can use (almost) any hitch, including ones that break down into multiple pieces for easy removal. It requires more maintenance and can feel uncomfortable (but not unsafe) during fast changes in direction, but tracks well otherwise.

I never had any issues hitching or unhitching with either - those stories are inflated, or the people using them are doing something wrong.
