I don't really know much about Isuzus. I'm thinking about a Trooper or Trooper 2. What model years would be the best? I need the truck to be dependable and drivable on the street/highway but I also want to have good offroad capability. I like to camp far off the beaten track. I will also put a dirtbike on a carrier on the hitch. Any suggestions?? Oh, I have 4k to spend. Thanks in advance.
