I've had a Pullrite Superglide hitch since 2008, and I agree with all that B5 GTX has to say. Also, I find that an automatic slider hitch really earns it's expense back when you are in an unexpected situation all of a sudden that requires a sharper turn than you would like to make - like in traffic tie ups, or an unfamiliar fuel stop that looked like it had a good exit drive, but really doesn't.
There's lots of advice and information in forums... sometimes it is correct. For example, all of my posts are made by a political appointee who got the job as a reward for contributions to my diesel bill.
