Congrats on your acquisition. We bought our 2014 CTD this past March as a Certified Pre-Owned with 11K miles. Yes, I highly recommend the off road race conversion. I waited to buy ours until the conversion was available. All your troubles will go away and your MPG will go up by 3-5 MPG. We routinely achieve 55 MPG on the hwy. Just got back from a trip to Orlando. Memphis to Orlando without a fill up and an overall hand calculated average of 53.5 MPG @ 70 MPH.
We bought the CTD to be our beater. Since March we have racked up over 19k trouble free miles. Well, my wife did have a blow out a couple of weeks ago. Thankfully, I also did the Verano spare conversion.
