Here's a tip. If you are traveling with more than two people total, you may find the 4 door Jeep an optimal solution. In addition to more room for passengers to enter and exit the back seats, you'll also have sufficient room for luggage. The "trunk" is considerably larger in the four door model. More info on Jeep models.
The 4 door Jeep has about a 20 inch longer wheelbase. Extending the frame allows the rear passengers to sit in front of the rear axle and wheel hump. Most agree the 4 door Unlimited is best for overland travel with steeper and more open terrain.
Performance on pavement is an important factor, and that’s where the 4-door rules. The heavier and longer wheelbase of this model makes it more stable on any road and provides a more balanced and comfortable ride experience, like that of an SUV.
