Which SS do you have will determine what slide design you have. The Schwintech (sp) in my opinion is easier to work on as the motors are up top behind the gaskets. My '13 3100SS has the Lippert which is under the dinette. Can't imagine how hard it is to get at the motor for replacement with the 3 inches of space between the floor of the dinette and the deck.
