Well I've decided on it and it's going to happen by the end of this year. I'm getting a GMT400 suburban no matter what. The only problem is i don't know to much about them (and I don't want to annoy my neighbor) so I was hoping I could get some general knowledge about issues, things to keep note, what to look for when buying, etc. I also want to know things like alternator output and can i add an overhead console even if it doesn't come with one (biggest thing i want to know is that)
