No, the big riggers are running the same DPF systems we are, only bigger..And yes they are having hell with them too along with horrible fuel economy. The only difference is they sue, since downtime to a trucker is livelyhood going up in smoke, or soot. I have a friend who works for CAT, and they are working on lawsuits from truckers and trucking companies all the time for downtime resulting from emissions equipment failures.
I would like to think the air is better since the arrival of the DPF, EGR, and Cat Converter, but I seriously doubt it, and since they regen so much and burn so much extra diesel, I would bet the air quality is worse.
2012 6.7 Cummins diesel Ram 2500 std cab, 4X4, 6spd manual, 3.73 posi, something underneath fell off at 5k miles with Rollin Smoke Diesel and H&S helped me out.
