they don't seem to warn or caution DPF's on their site, somebody's buying them I pulled 42,000lbs. down to Indy Thursday and they're light units.
Side note: IN. has the worst roads in the nation, maybe north america, obviously the corrupt government there is saying prayers for the potholes instead of fixing them...I-65 looks like a third world war zone, disabled vehicles with wheel problems all over on top of the weavers trying to avoid them, some 2-3 cubic feet, tens of thousands of them..this is not new been going on for years..travel IN. at your own risk, I avoid it at hours premium, time wisely spent.
