Last I knew gas trucks had fuel filters, transmission filters also. Gas vehicles also have emissions systems that fail. I replaced an EGR valve on the wife's car about 4 years ago. I can't say I know but a couple of people that own newer diesel trucks and they don't have problems yet, but I do agree, it can be a problem but I do think they are getting better. Keep this in mind, this is the future of diesel engines, like it or hate it. It the same for everybody, tractors, light trucks, big rigs, heavy equipment. We can whine about it or adapt. This is just like the late 70's and early 80's with gas vehicles, people whined and ***** about the emissions stuff but I don't read anybody complaining about it now on gas vehicles.
