I currently own a 01 QC 4x4 CTD, looking to add an 08 to my work fleet. Has anyone experienced any challenges with the 08? Want to get back into a ford but my truck is such a work horse will be staying with the cummins. Not familiar with the new emissions stuff, and looking at the list(s) of aftermarket items alot of you have, its alittle overwhelming...would be looking to maximize my mpg if anything down the road. I tow boats and trailers daily, nothing over 5k lbs. Thanks for any comments!
