I'm trying to decide if I should buy a pickup. It's an 85 GMC three quater ton 6.2 liter diesel. It has 140,000 miles, automatic, 4x4. It's a really nice truck prety good paint strait body nice wheels and needs new tires, plus verry nice sterio. But I've been told that diesel's are just big piles but this is a really nice truck. What do you think? It's my first truck and a dont want to mess up with this one. I will be going 4 wheeling, hauling a horse around, going to work and going to school. Maby somebody can give me some imput on the diesels. Thanks.
