I have a nice 2012 Dodge 5500 with a 6.7 Cummins with automatic trans. and a 19" aluminum Jerr Dan bed. 225,000 miles. Nice truck. It does have some motor noise the noise in the engine can not be heard untill around 1500 rpms then it is still a slight noise. We had it at the dealership because of the noise and truck had a small miss we thought maybe a injector was bad.They informed us it was wiring issues. We oked them to fix and spent $6k on a whole engine wiring harness and ECM. Then they were to tell us after we spent the money that the engine was 50lbs low on compression on cylinder four. So thats all I know about on the engine We just don"t want to put more money back into the truck. Any questions call 740-964-0989 We do not recommend driving it back home. It does start and drive and moves around just fine just makes noise. we are selling it as a mechanics special. You can come look at it prior to purchase, it is located in Orlando, Fl. 32805
