8.1 versus 6.00
Looking at used Chevy/GMC 2500HD's for a TT of about 10,000 GVWR. Would make sure that it has the tow package. We do travel in the Rockies and would like experiences and or opinions on the 8.1 versus...

The new tow spec has a min starting grade of 12%` 150% of the steepest interstate freeway max grade. Issues will be on forest service roads, local city roads, where I have been on grades into lo to mid 30% range. Yeah maybe only a few hundred yards.....but if you stall out and you LOW overall gearing is too tall. You do not move forward. Been there did that done that lots of times with older 3 so autos. Manuals no stall outs.
New 6 so has a 4.10-1 first gear. Vs 3.1 in almighty Allison, and 2.48 in POJ4m80/th400 derivatives.
