All the manual slider hitches work the same. You have to be wide awake and NEVER
put the tranny in reverse BEFORE
you slide the hitch. You probably cannot have cab to trailer contact when going forward, but in reverse you can jackknife in a heartbeat and result in a CRUNCH!
, probably including busting out the rear window of the cab.
An automatic slider is much better. You never have to remember to manually slide the hitch. There are two basic options - Pullrite SuperGlide and Reese Sidewinder.
The SuperGlide is a normal 5er hitch with three different options for mounting in the truck - below the bed floor with the original SuperGlide, above the bed floor with the ISR (industry standard rails, i.e., Reese bedrails), or a special OEM version that will plug into the factory optional 5er prep packages in new Ford and Ram trucks. Does GM offer a prep pkg yet?

The Reese Sidewinder is not a 5er hitch, but is an extended pinbox that works with an ordinary non-sliding 5er hitch to get the front of the trailer further from the cab when turning. An option is air bags built into the Sidewinder, called a 5th Airborne Sidewinder.
