I bought 2003 1500 hd new and sold it to my son this year for up grade to 2013 LML LTZ Z71. I towed for 12 years with the 1500 HD 373 gears if it had the 410 gears I would have keep it. Maxed out towing 8500 lb loaded fw was ok . It is a 8 lug wheel same transmission and towing equipment as the 2500 HD. The difference is 2500 HD has one more spring and 410 gears.I put mega flow exhaust and cold air intake that helped it a lot in towing.
