Unless your planning to pull in snow and mud I don't see the point in a 4X4, especially with a diesel. all diesel engines are taller than a gasser and mfg's have to accommodate for the front banjo housing making the truck sit higher. all my diesels have been ordered 2 wheel drive, never had a height problem.
