I'm looking to buy a quad cab for my growing family. The 3rd gen range of years seems to fit my budget the best. That being said, what should I be looking for? What are things to watch out for, i.e. common problems to see if they've been addressed on a used vehicle or something major or catastrophic to avoid that someone may be trying to off-load onto a potential buyer? I'm not looking to piss in anyone's cheerio's, but let me know if the 5.9 is 'more reliable' than the 4.7, etc. This isn't to incite 'your engine sucks, mine is better because that's what I have' kind of crap. Just coming to the pro's because you have pride in ownership and have potentially seen it all... I've seen a recall regarding 2wd ball joints or something like that. Should I avoid the 2wd? I don't need 4x4 although nice to have in a pinch. I'm in the Pacific Northwest too. Salt isn't much of an issue here...yet.
