I have a Big Horn RL3400. I want to move my sofa from the slide area to the rear in front of big windows and the recliners to the current sofa location. Has anyone done this? Also, does anyone know of a sofa sleeper that will work in this area? It has to be 27" deep or less and a maximum of 77" long because of slides. If not, does anyone have a recommendation for making the current sofa more roomy? It is fairly small for two adults to sleep on. Thanks for any help and suggestions.
