I have had two slider hitches! One was a manual Reese sliding hitch and the other is a Demco Glide Auto Slider hitch. I agree there is a learning curve with an auto slider hitch as the king pin is moving back as you try and turn to put the trailer in to a spot.
Once I had overcome this issue the Demco Glide is a breeze to back up with regardless of curves roads or not. I will keep my Demco Glide hitch as I like the firm grip and secured feeling towing with this hitch.
I for one will never tow with an AL tepee designed hitch with the off set hitch ball. I did a force diagram on the Anderson hitch to check on the forces that act on this hitch when towing. Let me just say I for one will not tow with a Anderson hitch.
