Years ago there was a Company in Arizona that added slide outs to RV's. Do a Google search and see if they are still in business and contac them. From a practical point, yes, you may THINK you are qualified to add a slide out, but the things that are IN a RV with a slideout are built internally. They add extra support header beams (steel/aluminum/wood) IN the top of the wall and on the sides to help support the Slide out when extended and STOP the slide out when extending without bending the existing wall structure. Your RV without slides will NOT have that reinforcement. THAT is the critical part of adding a slide room. Also, you probably have wires(120 and 12 volt) in the wall you want to cut out. You will have to add recessed floor rollers on the main floor to support and let your new room glide on. THIS is what the LCI Scwintek system uses. The LCI mechanism just moves the room in and out. The WEIGHT of the slide room is supported on those recessed rollers. There is NO weight applied to the LCI mechanism. You can probably do the job, but the framing of the existing wall and weakening of it after cutting the hole would be your biggest concern. The exact perfect rectangular cut of the wall hole and the exact perfect dimensions of your built room is critical for operation and sealing of the room in and out. Doug
