Nothing so far
Nothing will ever be wrong with it.
Very Quick
Average Gas Mileage got 12 during the first tank of gas now it is 15.8 mostly highway.
Comfortable
Great back seat room even for tall people
The V8 sounds awesome.
I just bought an 04 quad cab 4.7 v8 4x4. Yes, it is pretty lousy on gas, but the truck is plush, roomy and has serious power. I use it as a 'functional family vehicle', and I am very happy with my 1st non-GM vehicle. No complaints (except for gas mileage) so far.
