I'm not sure if the Carefree Add A Room has screen or vinyl windows but it does have a door option.
Outperforms all other low cost rooms on the market
•Features include: Web reinforced grommets, nickel-plated twist fasteners to secure side panels and skirting, and a storage bag. It has slightly lighter weight vinyl fabric and zippers than the LTD room.
•Sewn-in privacy panels can be held down on windy or rainy days with hook and loop fasteners. The room is completely reversible, so the privacy panels can be on the inside for convenience or outside for best rain protection.
•Three foot zippered door can be located on either end of the front panel.
•Sturdy side panel support rafters with brackets provide a better, stronger seal, because the room does not attach to the awning canopy. There’s no flimsy crutch tips to dent or damage your coach.
•Options: The popular Snapless Side Panels Upgrade Kit and/or a Hard Side Screen Door are available for the Standard Add-A-Room.
•Fits full-size roll-up awnings Fits most straight-sided RVs with awning rail to ground dimensions of 92"-121" tall. Fits Carefree Spirit FX, Fiesta & Simplicity, or Dometic/A&E, Carter & Faulkner models.
