I bought my truck in late 2003, and it just turned 100,000 mile last week. It has not needed anything other than normal maintenance (brakes need to be replaced, tires too). The worst thing is that the accelerator squeaks. I travel about 30 miles to and from work daily and it gives me a comfortable ride. The V6 helps passing the big trucks (I am glad I did not get the 4 cylinder). This is a great truck! I hope my next Toyota is just as reliable (whenever that happens).
It's just a comfortable truck to drive. It's not too big, but I sit higher than the cars around me.
Better gas mileage and suicide doors for the Xtra cab (like the Tundra of that vintage) would have been really nice.
