If this were a forum for OTR trucks then the answer would be: Do not buy any truck after 2002. But we are driving RV's that do not get a lot of miles. There have been next to zero problems with 2007 to 2010 engines in MH's. This would be those with a DPF. The 2010 and up have the DPF and SCR. Idling one of those newer units will result in expensive problems. Eventually the mfrs. will solve the problems. The EPA forced them to use technology that is not reliable. I have seen comments from industry leaders that it could take 10 years to fix the problems. There is a reason that large fleets ( Werner, Swift,etc.) buy about 30% more tractors than they actually need. This is the only way they can keep units on the road. BTW:2002 was the last year with next to no pollution controls. In 2003 EGR became standard and that too can be problematic. Truck mfrs. are doing big volumes selling complete trucks called Gliders. This is a new body and chassis with a rebuilt pre emission engine and the rest of the drivetrain. Slightly cheaper than a new truck and no headaches. However those trucks cannot enter California and soon the EPA will prohibit the mfrs. from selling these kits. If only we could arder a new MH with say a DD60 from 02 !!! On the bright side the new engines are very fuel efficient and the air coming out of the exhaust is cleaner than he air going in!
