The advantage of the gas version is the quieter engine, smoother transmission, and cheaper price. The engine mount also doesn't wear out prematurely.
All that is offset by the torque of the diesel, which is more useful especially with a full load, much better fuel efficiency, and the ability to occasionally seat 7.
