I had a short bed truck for around 10 years with two different 5ers. My first 5er had an extended pin box and I never used the slider. My current trailer does not have the same clearance, and I needed the slider every time I put the trailer away.
I started with a Reese Quick Slide manual slider. It was a royal PITA as I had to drop the landing gear, remove most of the pin weight, and then slide it back. Not the easiest process. I finally upgraded to a Superglide for the last two years with my old truck. They are expensive, but worth the money to never have to think about sliding the hitch again.
