It does sound like the truck is in pretty good condition with minimal problems, other than some, what seems to be minor/moderate, rust. Remember that with Michigan winters, rusting will be accelerated, so make sure things are protected/sealed well. I know you were saying that you only need this truck to last you a couple years, but it would be much smarter if you can use this truck for several years (5+ years). No sense spending $13k on a truck only to want to keep it for 2 years. If you do get the truck, remember to only put the necessities on it to start. You want to put lots on it, but you may really find out how easy it is to blow your budget and fast. So get the stuff you really need done, done first and then work on the other stuff.
