Aside from the Add-A-Room LTD., the Standard Add-A-Room outperforms all other rooms on the market. A great value in a quality white vinyl room. Sewn-in-privacy panels are held in place 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. Includes convenient bag for storage. 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. Fits most straight-side RVs with awning rail to ground dimensions of 92”-121” tall. (Fits Carefree Spirit FX, Fiesta, Simplicity or Dometic/A&E, Carter & Faulkner models.) Add on options include Snapless Upgrade Kit and Hard Side Screen Door.
