When GM changed to the 4.10 as the standard rear ratio for the 2013 HD, they indicated that it was because it improved fuel economy for most lower speed driving.
So, I wouldn't necessarily be giving up fuel economy? Also... would the lower gear ratio help driving over rough ground?
A few years ago we (DH)accidentally got on a BLM mountain forest road... while it was gorgeous our Silverado is not tricked out for that type of road. A crush plate would have been nice. It took about two hours to go 10 miles. Had to move a few logs and rocks out of the "road". No way to turn around or back out. Lets just say the GPS lied.
In 2003 we (I was driving)had a Ford 150 out in Colorado and took a "squiggly grey line on the map" that looked like a promising short cut... it was ONLY if you had 4wd. We did make it through the "short cut" without damaging the truck.
DH's coffee was all over the place... him, the headliner... windshield...dash... he didn't enjoy it much and was adamant that we never ever do anything like that again. Meaning me of course.
So... when HE got on the wrong road in GA... it was agreed we would never speak of it again.
That's a long winded story but it does illustrate the kinds of places I find fascinating and why I'm leaning 4wd...crush plate... etc.
So..does the lower gear help even when not towing?
