Might check into it to see which engine this is....

Early 07's had the 5.9 as indicated in the ad the OP posted, vs the newer 6.7 that did have problems with the DPF the first few years and most of those problems were with people who used them as daily drivers and never really got them hot enough from time to time.
Anyways, up until a week ago today I love my '07 5.9 and it sounds like a decent price. Didn't know they still made crank windows though..
My '07 was running perfectly and I was 36 miles East of Sturgis, SD when the check engine light went on and it went into limp mode. No reception, no traffic to speak of and I limped it back into Sturgis. 728.00 later I was back on the road. Had no. 3 injector go out at 82,500 miles. At 70,000 miles I installed an additional 2 micron filter in hopes of prolonging my injector life but I guess the damage had already been done.
