Need advice......HELP!! (buyin' a new one)

[cubber]

Hey y'all...I've been active over in the 67-72 forum, and have been helped a lot, and have even helped a few others. I am going to get rid of my lifted 05 F15 with 71K miles because it has been really problematic. I had an 04 Silverado a few years ago, and I really liked it. I have decided that I want an 04-06 crew cab 2wd, with the 5.3. I have located one that I like, but it has 160k miles on it. I think I can get it for around $9k. What do you all think? How long do these last with decent maintenance? What should I avoid? What should I try to find? Thanks for the help, and I hope to be on this side of the forums a lot more soon!!
