I had this company install my 15k SuperGlide in my 2014 3500 Ram. http://www.hitchcorner.com/
They used my industry standard rails with Curt no drill brackets. Its very clean and tight. Using these rails saved money and kept the height down. I still have 7-8 inches of clearance between bed and 5er. The 3500 is tall in the rear. Couple inches taller than my previous F350 (2010-so glad it is gone, blew 3 motors!).
I love my SuperGlide. Garysol, that is a great idea to get an atv winch!!! I am always calling a couple of buddies in the late fall and early spring to assist with taking it in and out.
