need help choosing a truck/suv

So I'm going to be getting a truck or suv soon but I need some opinions and ideas on what to get. I'm looking for 2002 or newer, probably about $10k tops. Id prefer to buy one outright but I only have 5-6k to spend. It must be at least an extended cab and 4x4, preferably v6 but v8 is fine. No Ford rangers, I need something a little bigger. I Won't be towing much if at all. From what I've seen everything in my price range has about 100 -150k miles, so I'd like some opinions on reliability as I'm planning on keeping this truck for a while.
