I too have the Husky 16K manual slide hitch. Not sure what is so special about a B&W, but I do know I can hook up to the Husky, pull the camper wherever I want, and unhook from said camper, and then repeat over and over. Pretty much seems like that is the same thing any other hitch would do. The four way articulating head works great, as I pretty much only boondock off of National Forest access roads.
I also pull doubles. 26.5' fifth wheel and 3,000 lbs. of trailer w/ATV's. I added a MOR/ryde pin box to the camper and it pulls great.
