I tried to search for this, but got no returns, so asking the questions. Trying to remove the sofa bed from the kitchen/sofa slide out of the Insignia 37MB so I can figure out where the slide is leaking when it rains. I see the four floor bolts/nuts and have removed the nuts and washer from the floor bolts, but the sofa will not budge. Cannot see any other bolts or screws that would be holding this to the slide. Has anyone removed the sofa bed from the slide out and how was it done?
