Trailer Life "Guide to Towing"
Got my Guide to Towing yesterday. I have a Ram 2500 long bed diesel 4x4, manuel 6spd so I checked these 3 Ram trucks and am somewhat confused by what I read. Larger truck, less towing? Ram 2500 RegC...

Not sure about the 2500 number but the difference in the 3500's makes some sense. The truck's GCWR is probably limited by the manual transmission, so the heavier DRW will have a lower tow rating. Tow rating = GCWR - truck weight.
Actually it does make some of the difference. The biggest effect is the final gear ratio. Heat buildup is a big part. The other factor with the higher gear ratio is the ability take off in reverse on a grade and the reverse gear ratio makes a difference also the ability to hold in park on a grade.
In the example, they all have the same final drive ratio. Yes, changing the ratio makes a difference, partly for the reasons you explained but also because a higher ratio allows more torque to be applied to the wheels without increasing stress on the clutch and transmission.
