First time buying a vehicle (it's used)?

Someone is offering me a truck for $1,000. There were a few other options, but they were all $1,500 or higher, and $1,200 is all I can really afford at the moment. What should I look for to make sure the truck will at least last me 6 months to a year? Should I walk away if the truck has a certain amount of issues?... show more Someone is offering me a truck for $1,000.

What should I look for to make sure the truck will at least last me 6 months to a year? Should I walk away if the truck has a certain amount of issues? Or should I expect that for $1,000 it's not going to be perfect?

Thank you.
Update: The truck is a 2004 Dodge Dakota (Quad Cab) SLT
