I have the Elite hitch. The Elite is an under bed rail system, and puck hitch system. Not sure about the Signature hitch but I think it’s an above bed rail system. When I bought my 2012 Ram it didn’t come with the puck option so I install the under bed system myself. I don’t find anything difficult about the Elite series, I like it. It was about the only below bed rail system at the time so I didn’t have much choice.
