2013 def??
I was speaking with a friend yesterday, he's an avid car/truck guy, he was telling me that the 2013 Ram pickup had been spotted in camouflage, one thing that stood out was the "larger" fuel fill door, meaning they must be thinking about it. I did a little digging and found this link that shows the urea tank. http://news.pickuptrucks.com/2011/07...y-pickups.html

I think getting rid of the EGR and DPF altogether is a better solution though with it's drawback of potentially voiding your engine warrantee.

From Cummins, "SCR is a technology that uses a urea based diesel exhaust fluid (DEF) and a catalytic converter to significantly reduce oxides of nitrogen (NOx) emissions. SCR is the leading technology being used to meet 2010 emission regulations."
In other words it replaces the cooled EGR as a means of reducing NOx. The DPF remains as a way to reduce particulate emissions.

Again, from Cummins with respect to their 2010 OTR heavy duty engines for Class 8 trucks, "Cummins 2010 engines will deliver what customers need in these challenging economic times. Cummins 2010 heavy duty engines utilizing SCR will provide substantial fuel economy improvement, up to 5%. SCR catalyst technology allows much greater NOx conversion efficiency, thereby allowing the engine to be fully optimized, which contributes to this fuel economy improvement. Another benefit to the improved fuel consumption is less frequent Diesel Particulate Filter (DPF) cleanout, thereby further reducing costs"
Cooled EGR reduces NOx emissions by reducing combustion temperatures by introducing cooled exhaust gases to the combustion process. This is an inefficient way to reduce NOx and explains in part why the 6.7 engines get poor fuel economy.

I plan on getting my Cummins before they are forced to use urea. First of all, I don't want the added expense of the urea. Second, it is a fuel economy killer. The locals running Duracrap and PowerStrokes whine constantly about the horrible fuel economy. My mechanic and his son in law are both running Duramax and they are reporting 8-12 mpg. A couple of the locals did DEF/Urea deletes on their new trucks and they are reporting 3-5 mpg improvement. Those guys rack up a lot of miles, so they don't care about voiding the warranty.
You can keep the def/urea, I don't want any part of it

Well DirtEater, maybe out in Oklahoma you have table flat roads, but this is Pennsylvania and we have hills. Lots of hills. These trucks are running the hills of SouthWestern PA and the Northern panhandle of West Virginia. If these guys were BRAGGING about the GREAT fuel economy, I would have said so. But they aren't bragging, they are whining.
All this smog crap is dragging down the fuel economy. First gen Cummins 2 valve 5.9l used to get 18-20 mpg empty or loaded, as did the 7.3 PowerStroke. That was good milage compared to the gas engines of the time getting 14 mpg empty and less than 8 mpg pulling 95000 lbs of trailer and mid size farm tractor. (And before you accuse me of not knowing what I am talking about, those numbers are hand calculated from MY Ford with 5.4, 3.73 gears and 4 wheel drive.)

If you can get 18-20 load you must be pulling a radio flyer. Also def will increase economy. Just look at all the places that have implement DEF and seen a rise in fuel economy. I know that in the tractor market is has been better.

While I have MY non DEF truck others may not be as lucky. I just read that the lowest freeze point of DEF is -11degC /12deg F and has a shelf life from 6 months to 2 years depending on storage temp. Here is an interesting Q and A from Cummins. Worth the read I though. http://www.fleetguard.com/pdfs/produ...es/MB10033.pdf
