GpnAZ - Nice work with the lens! Living in AZ for 15 years, I've seen many of the areas you've shot, but your work makes it a whole new experience. Congrats on the new TC hauler, nothing like a new hauler to get one enthused to get out and use it. Also, if you haven't already, please do write up on your jeep, mods, equip, powerplant etc... that looks just like the kind of thing I'd love to hitch to the back of my 3500HD & AF996.
Sidebar - DEF Tank discussion - True fact that Chevy does have a lousy location for their DEF tank, but after installing one of these
DEF Tank skid plateI have lesser worries about getting it punctured. In reality, even with the skid plate installed, it has 1/2" more ground clearance than the transmission cross-member, although it does run longitudinally with the frame rail so more area is exposed. Regarding mileage from a tank, 5,000 miles is the story I got from the dealer, but with a 5,000 lb. camper and 6'X10' enclosed trailer in tow, DEF mileage falls like a stone. I've had as little as 2,200 miles from a tank. I'm not crazy about having to run to Walmart or a auto parts store during a camp trip to get a jug of DEF, but as noted prior, the tailpipe is uber clean so guess that it does it's job. Not as big a pain as I thought it would be prior to purchase and to those that poo poo the system that will degrade your performance if you run out, the same thing happens if you run out of diesel! ;)
