Have you actually weighed your rig combo at a CAT Scale?
Yes, and the results tied in nicely with my estimation spreadsheet.

Have you add any accessories to your Chevy: step bars, tonneau cover/truck topper, etc?
Yes, and the weights for that are reflected in the spreadsheet.

Did you install the 3.73 gear set? If not, it was my understanding that only the Max Tow trucks with the 6.2 had the 3.73's. The 5.3 trucks had a max of the 3.42's.
