This link has some info about the Integrity (AS 5th wheel) as well as the squarestreams, I looked at pictures of one on ebay and it did not look/resemble anything like an AS product inside or out, just another 5W. I think if AS made an aluminum 5W based on the classic look it would be very competitive against other 5W's but it would be pricey to suite as well.
