I finally stopped and weighed my truck with the fifth wheel attached yesterday.

The wife and kids were eating lunch when we stopped and I didn't have time to unhook and weigh just the truck too so I'll do that another time.

My weights were Steer - 5000, Drive - 6440, and Trailer - 12180, Gross - 23620. When I looked up the following information, there are 2 different GCWR for the 3.73 axle ratio with 68RFE transmission.

Why 2 different GCWR?

How can I tell which one I have?
