Any of the trucks with Cummins engines seem to have very little DEF issues. The Detroits have been troublesome to say the least. All 3 have come down with the deleting computer virus

The place were i worked bought a new Peterbilt a few years ago first new semi they run about 20 trucks . It had a paccar engine the DEF system on it was a lemon . It had to be towed several times i felt sorry for the Driver he was a good worker and cared about doing a good job. This lemonbilt truck caused him alot of stress. My brother had a TV380 case the repairs cost on its DEF system i think would have bought us a nicer pickup then ether of us had ever owned.
DEF and covid are 2 things that real hurt this country lately .
