Welcome to the Planet. You will find a stock 1st gen Trooper to be very capable. There are 3 things that you should know about the truck.
1. The valves have to be adjusted every 12,000 miles.
2. There were some early casting problems with the heads.
Due to these 2 issues it is a good idea to do a compression test to see if you might have a burnt valve or blown head gasket.
3. The rubber parts are probably suspect. I would pay close attention to the vacuum lines. Brittle vacuum lines can leak and cause all sorts of idle issues, Also the bushings on the leaf springs are probably shot, causing the suspension to squeak and contributing to body roll.
