I have a 2000 4WD EB and a 2011 4WD XLT Plus (that's really an EB without the nameplate. Ford was in a contract dispute with EB at the time.), both of which I've had since new. My 2000 has 283K on it and the 2011 has 113K. The only non-wear items that have broken on the 2000 are the intake manifold (plastic) and the electronic component of the ABS. I took the ABS controller apart and sent the electronic unit out for repair and put it back together again. The ABS has worked perfectly for five more years now. I have the original coils, original O2 sensors and have never spit a plug. I have paid Ford to change the plugs every 100K using my plugs. Most everything else I do myself including oil changes and tranny fluid changes. It has been a remarkably reliable SUV. I've gone through a few alternators, ball joints, wiper motor, lots of brakes and other stuff, most of which I've changed myself. It burns about a pint of oil every 1000 miles now, but that's not bad for 5.4 with 283K on it. The windshield never leaked. The only issue the 2011 had was with the seat heater and I paid Ford to fix it. It burns no oil. I changed the plugs myself at 105K and it was remarkably easy. Took about 45 minutes. Nothing is in the way of the coils on the 2011. If you're buying a used one it will depend on how it was maintained, but I've had very good luck with the 2000 and 2011. The 2000 is built like a truck with the solid axle docraymond mentioned and I keep telling my kids it's the best car/truck I've ever owned (and I've owned 14 that I can remember). That said, the 2011 is pretty nice too with the independent rear suspension. It rides nicely, has 20% more HP with it's 5.4 3V than the 5.4 in the 2000, and gets about 15% better gas mileage than the 2000 did at the same age. I am looking forward to inheriting the 2011 from my wife when the 2000 eventually dies. They got rid of the 5.4 when they finally worked all the bugs out.
