I used to own a 2001 truck the same as yours. T.he 4:10 GCWR was also 18K. The 3:54 GCWR was 2000 lbs less. The limiting factor is the auto transmission. The manual transmission trucks back then had a 20K GCWR. I towed a 10K GVWR fiver and a lot of that towing was in the mountains, so I had my truck switched over to a 4:10 ratio.
