Beautiful F350 with only 153000 miles. We bought this truck a little over a year ago with the intention of driving it until it died and then putting a Cummins engine in and driving it for another 300000 miles. But our plans changed. The truck drives without any issues until we try to pull a heavy load up a steep hill, then it loses power. The Ford dealer says it may need the gaskets replaced. I'm only asking $9500 obo because it has the possibility of needing some major work done.
