I don't have any issues (or knot in stomach) backing up, but I am ultra paranoid. I don't let anyone help guide me in.. I always get out and look about 5 times... I have to see it for myself. I once had to back into a spot at night.. Couldn't see anything from the truck. I backed up a couple of feet and got out and looked.. About 20 times.. Took me 30 minutes to do it. lol.
I don't think any hitch helps the process... Have you thought of using a back-up camera at the end of the trailer?
