I had a 20K Curt slider (branded Ram) for several years when I first bought my truck. It worked OK, but was a bit clunky, and the truck/trailer chucked quite a bit with it. I found a virtually new B&W Companion slider for the Ram puck system last year on CL and jumped on it, and sold the Curt. I can say without question that the B&W is a far superior hitch, and I wish I would have bought one years ago. My wife even commented how much smoother the truck and trailer are with the B&W.
The Curt will do the trick, but there are better options IMHO.
