My cousin and DH had that plan in their KZ by removing the sofa. Problem is that Lazy Boy was the only one they found that would fit through the door. Not to mention pricey. You might check some floorplans from different manufacturers online and see if you can find what you're after, then call and get a contact for the manufacturer. The other issue they found was that the sofa was secured to the floor and when they'd get into removing it, there would be holes in the floor. They abandoned the whole idea.
