IF you have the owners manual for your model of hitch you will find the following
WARNING:
Never tow trailers in highway or high speed conditions with PRO Slider in the Maneuvering Position (rearward of the rear axle)!
Towing with the trailer king pin rearward of rear truck axle can affect weight distribution and may interfere with the towing vehicle’s handling and response characteristics.
Poor handling and response characteristics could result in death or serious injury.
IF you do not have the owners manual....look it up on-line and print out copy.
That way you will have the proper instructions and not have to figure out differences between 'Maneuver' and 'Tow'
