why the big differenc in tow rating?
Looking at the trailer life tow guides 2010 to 2011 for the Chevy/GMC Silverado/Sierra CC 6.6L TD DRW 4WD went from 15,900 to 21,000. What the heck changed? Yes I am new to this, wife and I will...

also a new version of the duramax
2007.5-2010 is the LMM
2011-current is the LML
they did a lot of upgrades with the 2011 a lot of nice things. only bad thing was the addition of the DEF tank due to more emission regulations
