I had a Quality S brand WDH with spring bars and clamps years ago. It was used when I bought it. The head was welded to a short shank (draw bar). I really liked that hitch but, I never knew what it was rated for. It just worked for our small TT and F150. The trunion style bar knuckles looked like the Reese trunion style knuckles. I'd almost bet a sandwich they would be interchangeable. With that said, I'd plunk down the bucks for a Reese HP dual cam from the shank to the chain brackets. That's what I did with our new TT coming back from a 5th wheel. If nothing else, I sleep better knowing it's rated for far more than we're towing and the parts are made to go together.
