As long as the the top of the hitch ball on your 2021 Ram 5500 with a CM RD Flatbed is not more than 13/16" above the non recessed portion of your bed then the Demco Recon Gooseneck-to-5th Wheel Trailer Hitch Adapter for Recessed Ball - Single Jaw - 21,000 lbs # DM8550046 you were looking at would be a perfect option for you.

This hitch has a 21000lb trailer weight rating which will be perfect for pulling most 5th wheel trailers with your truck.

If you find that your hitch ball sticks up more than 13/16" from the non recessed portion of your bed then the only option is going to be going with a 5th wheel to gooseneck adapter that installs on the king pin of the trailer such as the Convert-A-Ball Cushioned 5th-Wheel-to-Gooseneck Adapter - 12" to 16" Tall - 20,000 lbs # CAB-C5G. Keep in mind that this adapter requires a gooseneck hitch ball that cannot spin, and will only work on standard, non-cushioned or non-rotating pin boxes.

I included videos for both of the products mentioned for you to take a look at.
