Per my review above:
"2. What does the auto stop-start functionality feel like?
This was very encouraging. Like many of you, I generally find stop-start systems annoying and very noticeable. The Ram easily has the best stop-start implementation I've ever experienced. If the A/C is blasting, you would have no idea that the truck shut off. There's little to no vibration at any point. And the system restarts fast. Sitting at the stop sign with the truck engine off, I gave the sales rep a warning and then punched it. The truck spun the rear tires while starting the engine. So that little motor certainly adds some torque! This alleviates any concerns about possibly needing to start the truck quickly to avoid an accident. With 3.92 gears, you may have to be careful not to spin the rear tires off the line, especially on a 2WD truck."
