I got an 04 also, and the motor is just fine. The rearend though, that's another story. I have 130,000 on the truck and the rearend is howling like a lone wolf!!! This is not the first truck of this era I have heard of that has had a rearend problem. A co-worker of my brothers has had his rear end rebuilt once and it is howling again. I don't know if this is true for any other trucks from this time period, and I do a fair amount of trailering, but it has the towing package and I would like to believe that it should be able to handle it. I'm not too happy about having to rebuild the rear, and the $$$ to do it also, but I do like the truck!!! Just thought I'd throw that out there for you to check if you're thinking of buying it!!! Good luck with the purchase, Geof
