    Excellent product. Have used it for a year now and could not be happier. Completely stopped the shifting of my 5th wheel when someone is moving around in the bedroom. Easily set up after leveling the rig and cannot be stolen when used with enclosed padlock. Also acts as a pin lock.

    We have an 11,000 lb fifth wheel. This stabilizer took 90% of the movement out of our unit. The assembly directions could have been better, but it wasn’t that difficult to figure out how to assemble the stabilizer. Initial assemble took about 15 minutes with basic tools. After assembly, I was skeptical. The stabilizer seemed too light to really work. However, after only a couple more minutes to put in place and adjust, I was proven wrong. Once tightened into place, the structure was much more rigid than I expected. I then realized the design is based on simple triangles for a rigid design. The results were great. Most of the sway in our fifth wheel is gone. We are very satisfied, especially for the price.

    The heavy duty king pin stabilizer is great for stabilizing your fifth wheel; the difference is like night and day with the stabilizer on the tongue.
