Purchasing a new 2013 RAM, went to the dealer to look at the hitch in anticipation of purchasing a Torklift Super Hitch....I've helped my buddy install one on his FORD, they are bolt on units. Remove...
If its the same as the 3rd gen Rams, you have to lift the bed slightly to get it off. The Reese Titan bolts on under the stock hitch. When I had my 11' Lance I used a solid 2"x2" bar in the stock hitch and used U bolts to attach it to the Reese, creating the super hitch design. It wasn't as strong as the Super hitch but it helped.
