This is not answering your question, but my Open Range 5th wheel came with boot hangers and I've noticed that most of their models have the (traditional?) square type hangers, and many of those do fail, especially if equipped with Correct Track.
My boot hangers do have the V-clip and so far, after over 40,000 miles, have been OK-
