The new 13 is replacing a 11 Denali Dmax drw. It was a good truck with not one emission related issue in 70Kmiles. Had a leaking heater core replaced at 35K and had the front axle/diff mounting bolts/bushings fail and housing was trying to drop off of the mounts. Not sure why this happened. Replaced once and was happening again and truck never plowed or abused...

The 13 will never work REAL hard but will tow a 3axle 42' camper and a flat bed bumper pull on a fairly regular basis. He got the aisin auto and the 850 tq (3. 73's) eng. will report in from time to time as he puts about 60K miles on a year.

This 13 is so quiet you can't tell how fast you are going!

He is glad to be back in a cummins(all the ERS (5) are cummins drw from 96-04. 5. Only got the LML Dmax to avoid the non SCR Cummins.

The 1996-8 California-emissions 5. 9L had a dirty hot EGR system. The 2013 has egr, similar to what the other 6. 7s have but improved with no clean out needed at 67,500 miles any more. The engine produces less soot, very little in fact due to piston bowl and cylinder head chamber design, injection events, etc. The new emissions system uses urea (DEF) and I believe it will be a lot less troublesome and costly. Back in January 2007, DEF was a new idea, not matured, and the fluid was expensive and hard to find. Today, it is a mature technology and the fluid can be found everywhere like Autozone, etc.

Thanks Little Joe for your input and JD yes the Urea seems to be the cheap and dirty way to meet emissions as the VW diesel wasn't allowed in Commiefornia so VW went with the Urea to meet the demands of CARB. I guess in the long run it will be less costly DPF 1500. 00 UREA a lot less . Thanks all
