help buying a used 4x4?

[bigshrimpin]

Hello everyone -

I'm new this forum and I hoping that you all might be able to help me. I'm looking for a used 1990's Toyota 4x4 truck that's capable of mild offroading/camping (getting to some out of the way fishing spots . . .etc.). My budget is about 6k. After searching autotrader.com and cars.com it appears that there are a few 4x4 trucks in this price range.

I hoping that you guys provide me with enough information to help me pick out a decent truck . . . since everything in this price range has over 100,000 miles.

Where are the most common trouble spots on these trucks . . .
i.e. - Just want to be prepared so I don't get taken.

Also what is the best place to search for good deals on older 4x4's?
