Re: anybody switch from a wk2 (11-13) to a wrangler same years ?
I own both a 2013 JK Rubi (my daily driver, heavily modified for it's real intended use) and a 2014 WK2 Overland (wifes daily driver, stock) I feel I can add to the consensus here.
My honest opinion is that unless you plan to off road hard the JK just has too many compromises to be considered for daily driver status, let alone road trips. Mine is heavily modified, and as such it drives much better than it did stock, and rides better as well. Even still, it is substantially rougher than the WK2 and requires constant minute steering corrections... and cross winds push it all over the highway. Taking the hard top off is a 2 man operation, I say man... if your spouse is a girly girl she'll help you once, nearly dump the thing in the driveway and be done with "open air driving".
I love my Rubi, it is stellar in the AZ rocks, which is what it was purchased and built for, otherwise the WK2 is the ride of choice... even for short errands.
MPG, I was getting 20mpg hwy, 18mpg city when it was stock, 3.6L with 6spd. Now that it's lifted, armored, geared and 35" rock tires I get 15.8mpg hwy (72mph, less if I go faster) and still 18mpg city. I drive like grandpa.
