I've had this truck more than 10 years/136,000 miles, and it's still reliable. Changed the transmission myself @ ~ 100,000 miles for < $800 - hauled too much gravel for the wimpy 4-cyl. No leaks, no other major problems. Replaced power steering belt, repacked front bearings, headliner is falling apart, other than that, mostly just regular maintenance (oil, brakes, plugs & wires, etc.). I'm always amazed at how well it does in the woods in 4WD (as long as I don't need too much power). Hopefully I'll get 200+ out of it.
20 MPG is pathetic for a vehicle that has about 130 hp, 4-cylinders, and weighs less 2 tons. Don't ever expect to pull much more than your kid's radio flyer with this truck. Oh well, can't have everything.
