I'm the proud owner of a 2000 F550 7.3 manual dump truck. It was traded in at the dealership and I bought it. I'm pretty pumped to have an older manual diesel, although I don't have a dedicated use for the truck other than plowing the driveway. We live on a pretty good sized farm so I'm sure it'll get used.

So my question. Whats the best way to keep one of these fresh if it's going to get limited use. It only has 90k miles on it. If I start it up to running temp and move it around the property once a week or so will that keep things good, or are there other considerations to a 7.3 diesel that doesn't see the road much/ever?
