Any lift would be minimal for that exact reason.
A good friend of mine has a '15 LTD and loves it. But we rarely drive in snow or rain, so think the AWD would be more of a hindrance to mileage for times it would be a benefit. I have heard that while the XREAS is nice, it has more problems and more expensive to deal with than the KDSS. Also, doesn't the LTD skip some of the Offroad enhancements like the driving modes and the locker? Not nuts about the grill as much, looks like the pre-2014 models before the facelift.
My wife wants another full size pickup, but when I ask her if she will take it to work and find parking every day, she goes all silent LOL! My Dodge is a full size PU with a regular cab and 7' bed, and sick of it around town.
