For the guys that have NOT deleted your trucks and rack up the miles. How many miles did you get before the DPF was full of ash and needed replaced / cleaned. So far I'm at 111K miles and still going strong. I have read that the life expectancy is around 120K miles. I'm considering deleting my truck but I drive it for work and I have to replace it with something next year. I don't have to have a truck for work I just prefer to drive a truck and we have a 12K lb 5th wheel so I need to have a truck in the stables. If I delete it then I'll be married to it for a few more years and have to buy a car next year then do the driveway shuffle with the extra vehicle in the driveway.
