Look! Up there on the ridge. It's a truck! No, it's a Jeep. Wait, no, it's both. The Jeep Gladiator is classified as a midsize pickup, but it's certainly not your typical truck. It's probably easier to think of it as a longer four-door Wrangler with a 5-foot cargo bed in place of the traditional cargo area. Rugged Jeep character and off-road prowess, the only convertible truck on market, offers bigger back seat than other midsize pickups. 3.0-liter diesel V6 provides 260 horsepower and a stout 442 lb-ft of torque.
