My mom has an 02 Trailblazer RWD LT, 105k miles. Great vehicle.
fuel filter, spark plugs, brakes, tires, oil
Its due for a good overhaul though. 8 years and 105k miles, needs some bushings, trans/cooiling system flush and fill etc.
Very reliable.
It is also much larger on the inside for people and cargo than the jeep and explorer are.
My vote is a Tblazer variant.
