If you have the Custom Underbed Installation Kit for B&W Companion 5th Wheel Trailer Hitches, # BWGNRK1116-5W and the B&W Companion 5th Wheel Trailer Hitch w/ Slider, # BWRVK3400-5W you can not use a rotating turret type king pin such as the Revolution/Sidewinder. B&W clearly states that this fifth-wheel trailer hitch is not compatible with Sidewinder or Revolution king pins. and to not use any device that changes the pivot point of your trailer's king pin with this hitch.

You will need to change hitch or pin box, I suggest the pin box. First identify the pin box number off of the 2017 Rockwood Ultra Lite 5th Wheel. You should see markings such as LIPP 1621 or Lippert 1621 or a 1716 or another set of digits, this identifies the pin box type, and thus the bolt pattern. From that information we can identify what is available. An example is that if you have a 1621 pin box you can replace the Reese Revolution with a basic Lippert 1621 5th Wheel Pin Box rated at 15,500 lbs., # LC1191191. Or, what I suggest, something such as the Gen-Y Hitch Shock Absorbing 5th Wheel Pin Box - Lippert 1621 and 1621 HD for 18,000 lbs. to 3.5K TW, # 325-GH-8040. This is a shock-absorbing pin box that provides a smooth, safe ride. This has a pin weight scale built in to help you balance your trailer, the all-in-1 box has no air bags to refill or small parts to replace with a weight scale lets you monitor your vertical load up to 3.5K pin weight.
