The other thing that scares those of us that work in agriculture, hunt or do anything else offroad is that hot smell you speak of. What if I'm out in a customers field and start a fire? When we first got cats on the gassers in the '80s they were a problem. With my '98 454 after many checks I never worried about it. The cats were shaped to shed stuff and did not get as hot as earlier ones. Now we have DPFs. I haven't heard or even read first hand reports of Dmaxes being a problem but I have of the Dodge and Fords. It's not a risk I'm willing to take.
