A dealer who has no clue? What?
Pull the back of the sofa down and there should be 3 (three) screws on each side on the bottom of the sofa towards the back of the sofa. There should be some in the front too. Not sure how long they are as I haven't removed them. It's quite possible they were over tightened and the heads popped off. I have to remove my screws and slide the sofa about 1/4" as it hits the wall of the camper. Doesn't do it as bad since I removed the air bed. I had thought about taking the entire sofa off the slide and removing the silly looking front legs. Since they don't have a purpose, I thought the legs would look better in a drawer in my garage.
