You can download the Jeep Badge Of Honor app to your phone. Tells you where and what all the bade of honor trails are. You can check in from it and everything. That's how I did my last one down in southern Mo anyway.
I tried this on Saturday and although the mileage was better I saw no gain in battery mileage. Personally I would think you would just cause premature wear on the tranny as it wants to hold it in M8 instead of downshifting like normal.
