When did DEF become required ?
Thinking of upgrading to a DP. I want to avoid having to deal with DEF. What year models did it become a requirement ?

According to what I have read, engine manufacturers say you get better fuel mileage due to the increased horsepower and torque, if you want to believe it. The problem I see is the cost to replace the system. On a 2007 with the regen system, the cost according to a factory rep is about $9,000. I do not know the cost to replace a DEF system.
Those are some of the reasons I purchased in 2003 that has a 2002 chassis with NO pollution required equipment. In 2003 the EPA required motorhome chassis manufacturers to add a cat converter and an EGR valve.
I get 8.5 to 9 miles per gallon towing a 6000 pound Hummer. I AM REALLY HAPPY!!!!!!!!!!!
