You really need to look at Ford's Towing Tables if you want to know that 3.73 get in all the different configurations. The 2016 RV & trailer towing guide for Super Duty, F-350 4X2 SRW Regular Chassis Cab config shows a GCWR of 23,500 with a max trailer wt of 16,200 on 3.73 gears. Only way to get into the 20K range is to go DRW.
