Very cheap to keep. Bought new in 2000 and now has 99k miles. Parts replaced in last 12 years: Front brakes (rear drums still good), radiator (plastic part of rad cracked at 10 years / 93k) $136 from napa, ball joints (added the type u can grease) forget cost, was not a lot, 2 sway bar end links - $60 installed by shop, cruise control switch $115 installed by ford at 85k, rear door latch cable broke $55 dealer part. Paint on hood and roof just now starting to fade (never garaged and in Florida sun) still looks good - but will be faded by next year. Remote door locks (key fob) and lock switches went bad early, never fixed.
key fob and electric door locks went bad around 30k. Never fixed, use key for access.
2.5L Engine, Manual, 4.10 axle. Actual mileage was 69K last year. I made a typo on my 10 year review, but still low miles for the age of the truck. Most Reliable vehicle I have ever owned. It may be slow, the paint may be pealing off, and the design is 20 plus years old, but I would not own another vehicle for everyday use. I have no worries or concerns with this truck. I expect to get another 10 years out of it. Maintenance cost for the last 11 years has been about $250. Two oil changes, one thermostat, one battery, that's it.
I bought this truck used in 2003. It has been the most dependable vehicle I have ever owned. Gas mileage isn't that great (20 mpg), but a very strong performer. The 4.0 L V6 comes in very handy when you need it. Great acceleration for passing truckers on hills in the mountains. The 4WD has performed flawlessly in the winter, and I have pulled lots of people out of ditches and towed them up icy hills. The only things I've replaced on this truck are the front brake shoes (80,000 miles), a couple sets of tires, and the windshield. The only modification I had installed was a dual exhaust cat-back for $300, which greatly improved the power.
The 360 degree overall visibility is great to have. A nice high ride in spite of it's size.
I eventually had to disconnect the cab light, because it kept turning on by itself, the doors tend to make a clunking sound while driving, and the dash controls are a bit flimsy.
My truck is a 2.5L manual with a 4.10 rear axle. I bought it new, and now have 39k miles on it. I have changed the oil twice. It sat for a few years, and it fired right up with a jump start. This is a very reliable truck. Acceleration is slow, but because of the gearing, it has no problem climbing hills, even with its 119hp engine. I replaced the cooling system thermostat recently because I needed to have it smoged, but it ran just fine with it stuck open. Clutch, brakes, and tranny are still fine. This is the best vehicle to abuse and neglect.
