I think that you will find that all 5th wheel hitches can be eaisly removed. The difference is in the mounting system. Some have rails mounted side-to-side across the bed (Reese and Drawtite), and some have them mounted for-aft (RBW). The Turnoverball uses some kind of mount under the bed. The mouning rails stick up about 1" for the Reese and Drawtite.
In any case, the 5er hitch is the way to go. Very easy to hook up to.
