Well, when observing the average MPG reading over time, I noticed it really dives when stopped at a light. Otherwise the truck isn't that bad on gas. Now I know that reading is far from perfect but if there was a way to add that option that wasn't prohibitively expensive I wouldn't mind doing so.
Considering the responses I've received, this is likely where my investigation ends.
Thanks for the welcome. I'm new to Ram ownership as well. Also, I saw that Ford comment earlier. I learned to drive in an F-150 and have owned a few Fords since. I'll pass, I'm quite happy with Ram.
Ya, a buddy drives F150s and asked me why I didn't want one. That would be a hard NO and pass, just like you.
I believe it shouldn't be too difficult to find real test results from users as to how much improvement you might expect in mpg.
AFAIK, the improvement is more related to manufacturers' EPA testing and nothing too realistic in the real world.
What is real though, is the added wear & tear on batteries & starting systems. And, my Ford buddy absolutely hates that feature on his truck and tries to remember to disable it after every start.
Maybe, if your brain is still sharp enough, you can incorporate a subroutine where you automatically start your vehicle even during 'O $hit moments' where you need to instantly vacate the area. I'm not convinced the potential minuscule mpg savings is worth the risk, for me and my truck at least.
YMMV
