I reached out to the manufacturer of Hidden Hitch which has been discontinued and replaced with Draw-Tite in most instances. The model of hitch you have has been discontinued but I was able to get the specs for you from the manufacturer. There is not a rating for use with weight distribution systems so you will be limited to the 5,000 lb capacity.
If you want a system rated for 6,000 lbs (with weight distribution), I recommend the Draw-Tite Multi-Fit Motorhome Trailer Hitch, 24" - 46"... view full answer...
