I know there are certain model years you may want to avoid because they have a tendency to burn oil. The Trooper is a good little rig and it is over built. I have owned several Isuzus over the years and they were okay vehicles. I have been more pleased with my Montero's because they seem more reliable and versatile. The Montero also came with a rear locker from the factory and ARB makes both front and rear lockers for the Montero. ARB makes a rear locker for the Trooper, but it can be pricey. Gearing options for the Trooper are also limited. The Trooper is a great vehicle and offers a lot of bang for the buck, but I think the Monty is a better option. Give them both a try and see what you like.
