(just kidding) Welcome to the best Chevy truck site on the internet.I say the K/10 and I am sure you will continue to get the same responce here.Since you said the mechanical was not a problem that is half the battle and being that it is a 4x4 it should be easy to crawl under it.I would check the frame and everything else you can see for rust.(Surface rust underneath ok,Flaking peeling rust bad,walk away) Just my .02.
