The new one have the new gov regulated exhaust on them that dump raw fuel in them to burn out the cat . After 4 burns at 1200 degrees the exhuast is dead ! And you will be helping me keep my job :-)
He does not get 20 mpg towing a 5th wheel, and WTF are you talking about "After 4 burns at 1200 degrees the exhuast is dead !"
You've been fed lies Newride. The diesel particulate filter (DPF) collects all the "black smoke" and keeps it trapped until regeneration. Diesel is injected at a metered rate to burn off the particulates. This is normal and the emissions systems are warrantied (by a government mandate) for at least 120K miles. A "dead exhaust after 4 burns" is highly unlikely, and if it does happen, it is covered for free.
Stop talking nonsense.
