Update on our noise. We took it to the local Ford "big truck" shop and they kept it two days before telling us "what noise?" It's a truck. Trucks make noise. John drove down, took them for a test drive, waited till she started singing, then said THAT noise. OH, THAT noise; OK we'll look at it; we may call Ford to see if this is normal for the V10 engine.The PC has been there another two days and we hope to have an answer by noon today but I have a feeling they won't have fixed anything. We told them we need it to camp in tonight and asked if it would be fixed. Their answer; well, it will be ready to pick up either way... implying a good chance there will be no fix. I LOVE car dealer repair shops. We should have cancelled our local appointments back in May and camped out at the Ford dealer in Indiana to wait out the week until they could look at it. We are going back through Elkhart in July so we may book an appointment with the Ford dealer there and see if they can quiet her down a bit. At least they know what the engine is SUPPOSED to sound like. What noise, indeed.
