As someone with the eTorque, I don't know if I would get it again. I live in the DFW, TX area so the start/stop is used quite often which I do like. But if you're not using start/stop, there's no MPG benefits. The only issue I've had is that with the truck still running the tach went to zero even though the oil pressure still showed normal (With start/stop, when it shuts off, the tach goes to zero and so does the oil pressure and of course the engine shuts off). It did this three times. However, after a software update during my last oil change, it hasn't done it since. As far as the extra 100 lb-ft of torque for the first half tire rotation, I did some towing a few weeks ago (~3000 pounds including trailer) and I really didn't notice it starting out any easier than my regular 2011 Hemi. But, I didn't have a non eTorque right there to compare it to.
We'll see how the eTorque is doing two years from now to see if it has become problematic. For reference, I bought mine in August of 2018 (July 2018 build date) and I have ~35300 miles on it as of today. I have the 3.21 gears, by the way.
