I agree that to hook up you've got to come in dead straight--this is because the wedge which keeps the pin straight in the hitch while driving will also prevent the pin from seating during hookup if you come in at an angle.
To help me come in straight, I've put 3 pieces of white tape vertically along the center of the pin box:
When I'm backing up to the box, it is real easy to see whether these 3 pieces are aligned vertically. I hook up on the first attempt most times now.
I've also added one of those teflon skid plates to the box:
As you can see, I had to cut a notch in the plate to fit around the wedge, but that's easy enough if you measure carefully.
As for releasing the hitch, the biggest problem I had at first was that the release handle was sometimes hard to pull. After raising the trailer to take the weight off of the hitch (the 1/16" to 1/8" gap advice in a previous post is excellent), the trailer may still be pulling the pin back on the rear of the hitch due to a slight slope, your chocks, or whatever. Try putting the truck in reverse and releasing the brake (do NOT step on the gas!) to eliminate this pressure and the handle should be easy to pull.
