I'm going to look at a 2004 LLY tomarrow and am wondering if there is anything specific I need to look for or listen to while i'm looking at it. I was also wondering what is the common problems these trucks have? I have read a little on the overheating issue and I have seen alot of people who have posted on needing to replace head gaskets. Is this something that fails on the lly's often? Thanks for any info or help.
