What is the trailer GVWR. Length and brand doesn't tell us much.
IMO PullRite Superglide is at the top of the heap in auto sliders.
I have a '03 2500 Dodge/Cummins short bed and use a old 16K Reese manual slider since the truck was new. My trailer is a old '97 model 32' long with flat square front corner profile.
My hitch is set up zero over the trucks rear axle so I get the full 11" of travel aft with the hitch.
I don't need it around fuel stops.
However when I pull into the camp ground and come to the first stop I flip the slide lever handle. The pin slides 11" behind the truck rear axle which creates less steering input while backing.
