At one point I had a 2005 QC 2500 Hemi 4x4 w/ 4.10. My 2011 QC 1500 4x4 w/ 3.92, (similar gearing), and the newer more powerful Hemi downshifts less than my older 2500. In addition to more torque I would expect my 1500 to weigh somewhat less than my solid axle 2500 did

I have a hill, close to my house, that has an 8% grade, (according the the warning sign). The hill is about 1/4 mile long. The 1500 does not downshift or even slow down. It does kick out of "ECO" mode where I assume all 8 cylinders light up

Towing my trailer? Yes the tranny kicks down and the RPM goes to 45-4800. This is perfectly normal for a gas engine towing a 31ft 7-8,000lb trailer. The Hemi is very happy to run in this RPM range. Again, the newer Hemi feels stronger, pulling my trailer, than my previous 2005. Likely the higher torque in the 2011
