I am still driving my '04.5. I took delv. in Feb. of '04. It has 176k on it and counting. It is used as a DD also. I change oil,filters,add fuel as necessary and go. We did 7k miles this summer in 50 days with 5th in tow and not one problem. This mileage included crossing the Rockies twice and the northern Cascades twice. Oh by the way I am still running the stock fuel pump. The trans got rebuilt last year at 154K with HD parts. The interior and body still look new. No rust, cracked dash or worn out seats. JME. Good luck with yours.
