Thanks for reaching out, Jeff!
For standard base rails you'll need the Curt Custom Fifth Wheel Installation Kit # C16427-204 for your 2018 Ram 2500. This is a custom kit so you won't need to drill into the frame of your truck for the installation.
Then for a 5th wheel hitch I recommend checking out the Curt A25 Slider # C35DR for a short bed or Fixed # C86BV for a long bed. I really like the A series hitches because they have interlocking jaws and a fully articulating torsion head so give you a really comfortable towing experience. The 25,000 towing capacity is nice too since it just increases how many 5th wheel trailers the hitch is compatible with.
I've attached some review and installation videos for your reference!
