carringb: I think you are confusing HD trucks and RV's. Class 8 trucks use a more robust DPF system. They also have many more regens. In one year a Class 8 truck will travel 150,000 miles. A MH might go 7 or 8,000. At that rate an RV DPF would be more than 20 years old before needing any emission repairs. Navistar is a whole other story as the engineers were arrogant and dumb. They insisted they had developed a system that would be better than the Cummins unit. Of course they were lying! The Navistar engines were and are junk ( mF13 and up). Early Cats with DPF's are just as bad. Our 08 Dynasty ith an ISL has about one regen per year! Still as strong as ever. I might add that emission problems will get worse very soon. The EPA, CARB and impossible to obtain fuel mileage demands from the Gov. will cause nightmares.
