Thanks guys! Always appreciate the feedback.
As for MPG...well the long answer...the 6.7 is an interesting animal. Clogged with EGR, DPF, SCR and DEF emissions systems, the fuel economy suffers and so does the power (I'm told there's another 200 horses there, but this truck never left me wanting for more power!), while the truck blows 0 smoke (something my wife loves and I don't hate). I've read lots on the merits of deleting all of this (my county does not smog), but resale and possible longevity of the powertrain may suffer in the longterm even though the tranny is rated to over 1100 ft/lbs of torque. As a result, I haven't deleted and tuned. Lots of info out there that guys are getting in the low 20's empty and very high teens when towing massive trailers with a deleted 6.7, but my experience with the stock truck is less. 14-16 empty, 12-13 fully loaded with everything we own (the camper loaded with bikes, skis, a KTM, all gear to play, etc etc.).
