 This truck is junk. It has left me setting over and over again.  White smoke, stutters at 2500 rpm, blows turbo clamps, just replaced a seized up egr valve. Have had new rear-end, 3 new radiators, egr valve, egr coolers, and the only thing they do is say "we reprogrammed the pcm" Never works right. The outside and inside design of this truck is over the top, the engine just needs help. Never again.
