I believe that pin box can be hooked up to a Trailer Saver hitch, probably a BD1 or BD3. Is it worth it - yes. Their hitches are of the highest quality and will protect your truck, trailer and back side. The weight isn't super critical with a Trailer Saver as you air them up to a tow height mark, the heavier the pin, more air. I have the TS3 and if things get really bumpy, I can air up the hitch for an additional 2" of bed rail clearance. Many times short/light fifth wheel trailers have worse rides than long/heavy units. My trailer tows at 10k#. The hitch is worth every penny I spent on it.
I watched the installation video. It looks like if you carry your tools, you can remove the capture plate and lock the rotating part out and hook up on an angle if needed. Then run as a standard pin box until conditions are better. By the way, the video operator's technique with the torque wrench is terrible. No way is he going to get an accurate 200 ft-lbs of torque with a 1/2" Harbor Freight wrench. Many good quality manufacturers make 1/2" wrenches to 250 ft-lbs.
