No, it is not true that ALL jeep models are towable, but most of them are.
Some examples of non-towable Jeeps are the 2WD Liberty, all Compass models, and some AWD models of the Grand Cherokee. But if it is a 4WD with a transfer case that has a selectable Neutral position, it is probably towable (and that's true whether it's a Jeep or some other brand).
