I spend all morning yesterday going through the process of buying a used Ford F550 dump truck, it was a 2004, 6.0 PSD with 82k miles, it was an old brickmen truck. I went down to the ford dealer to get the truck checked out, they didnt have a lift to lift the truck up to check it all so they sent me to a different dealer. I got to the dealer and they were busy and their lift to lift the truck was in use, so i asked them just to check the main items (engine, front brakes were spongy, drivetrain, etc..). Other than the rust on the truck the only things it needed were new front brakes ($500) and a parking break ($200), they said everything else looked ok. I was going to buy the truck untill, i was driving on the highway and all of a sudden i hit a bump and the turbo stopped working, the highest speed i could get the truck was around 40mph. So i returned the truck to the owner and said that i would not be buying it. I wasnt a bad price ($10k) but it had very high hours on the engine (6400) and i was worried about that. It was a long day.
