Since i'm selling my 4runner to buy a tow rig, i've been looking at tons of trucks for sale. I started out wanting to find an older ford gasser but I've decided that i like the '88 and up chevys better. They look much more updated than the older fords and are overall a "nicer" truck. I've also come to realize that in my 3000.00 and under price range that i could potentially pick up a 6.5L diesel in either a 2500 or 3500 truck. I guess my question(s) would be, are these good dependable trucks? Are there any known trouble areas in them? What kind of milage is acceptable when looking for a good dependable daily driver/tow rig? Thanks for any and all input on the subject.
