Nothing has gone wrong with this truck. It's huge! It has a lot of 'slop' in the steering, like a Lincoln Town Car, but that's a good thing because if it had 'deft/sport-like' handling you'd flip your wrist and have 18 feet of vehicle encroaching the other lane!
People say these get terrible gas mileage, but I get 13.7 on the freeway, and about 12.5 around town. That's better than a Hummer! It has major torque and even doing 80 mph, never turns more than 2200 rpms!-Engine wear-not likely!
The interior amount of lights (especially the awesome reading lamps for the two rear seats), the multiple cigarette lighter plugs, and copious amounts of drink holders all make this truck very convenient for driver and passengers alike.
In any case, they've been discontinued by Ford, so the selection is limited to whatever you can find at a used car lot, someone's front yard or remaining stocks and wherever that may be. That's probably not a bad thing, either.
Nice you like the truck. However, a technical comment:
In modern engines, wear is NOT necessarily related to engine rpm. Modern technology of materials and the use of advanced alloys have overcome some commonly known traditional constraints: Thus, IF lubrication is correct, a high revving engine will have no problem reaching 200K or more. See, for instance all those VTEC honda's (and the majority of toyota's with multi-valve engines) which use high revving engines for 20 or more years now.
