I'm looking to buy a truck. Want a late-model (2000-2004ish), low miles, less than $30,000. Requirements: extended cab, tow package, cd player. Nice things would be diesel, 4x4, 8' bed. It will be used for towing two horses maybe once a month, getting hay for said horses about as often. I'm looking for good gas mileage empty and loaded, ease and comfort of driving (for the SO), and durability. I plan on keeping this truck forever if it will last. Any input guys, maybe differences between the diesels available? Thanks in advance!
