Actually, that isn't true. The GVWR of any GMT800 (2000-2006) 1/2 ton Suburban is 7200# regardless of axle ratio. My 2005 with a 3.42 was 7200#. Where you gain the 1000# is on your GCWR. The 13k would increase to 14k#.

Thank you for that note - looking at the owner manual, I see now that the column heading is "Maximum Trailer Weight" and the value (7200) just happens to coincidentally be the exact same as the GVWR on my door sticker. So I got a bit confused!
