The 4X4's look really sprung high, anyone know the height difference?

Anyone know the reason between the 8 gallon fuel tank difference on the two models (2WD has 34, 4WD has 26)?

All the new diesels have to burn an additive in a seperate tank now, maybe thats why the fuel capacity difference. As far as height, just get a drop hitch.

Actually Dodge touts that they don't need an additive like the competition......Urea is the additive.

I believe the 2011 Dodges will have the urea tank. I heard they had gotten a pass till 2012 but are going with it anyway in11

Actually I just read it will only be on the 2011 cab and chassis trucks in 2011, possibly all others in 2012

I have a 2011 mega-cab 4x4 Laramie diesel dually. No urea and 34 gallon fuel tank.

Website must have a mistake, shows all 4X4's w/26 gallons.

Tank Capacity 26.0 gal. 26.0 gal. 26.0 gal.

I didn't have the DPF in my 2006 but there was an EGR valve in the engine which I found out after I complained on cumminsforum.com about dark, dirty-looking oil after I had changed it and just ran around the block and checked it.

I think the Cummins guys would say that if the urea system would get rid of the DPF and EGR they would take that and smile. Urea is not that big a deal really.

I also was told that they are tweaking their straight 6, and still trying to make it as reliable as it is presently. Doing testing and are around 380 hp and 770 tq, more to come in the future

The Cummins has no problem with reliability at 500hp/1000tq. Cummins does twin turbos better than anybody. Triples too.
