For most of 3 years, I pulled the trailer in my signature with the 16k Sidewinder when I owned a 1/2-ton Silverado. Tracked fine, I highly recommend for short beds to save the cab of your truck. A bit temperamental at times hitching or un-hitching, seemed to be due to binding due to the angle not quite right. But that aside, doesn't carry the cost or weight penalty of the Pullright Superglide and unlike manual sliders, you never have to remember to engage it.
With a long-bed now, I have removed the wedge and pinned the arm to allow it to function like a conventional pinbox. And the hitch itself? A Reese Titan 16. Zero problems there.
Hope this helps!
