Long or short bed? You're going to get a lot of opinions here: Slider vs. non-slider, gooseneck, Andersen, conventional 5th wheel hitch, etc.). What kind of puck system is being installed? Is it just for a gooseneck (like a B&W turnover) or is it more like an OEM puck system with 5 holes?
Personally, I have owned a Pullrite Superglide and now use an Andersen Ultimate Hitch and I love it. Easy to get in/out, quiet and solid operation and if you have a short bed, it can give you more cab clearance potentially avoiding a slider hitch.
