What’s the difference between the Jeep Wrangler and the Jeep Wrangler Unlimited? The difference is how many friends you can bring along for the ride. The Wrangler Unlimited is the four-door version of this veteran off-roader. Think of it kind of like the crew cab for a pickup truck, but this one is all Jeep. Some Wrangler trims only come in the Unlimited configuration. And some Unlimited trim levels can add the Altitude sub-trim level. That’s a lot to take in, but we’ll walk you through it in this preview and model guide of the 2020 Jeep Wrangler Unlimited.
