From my limited experience, I would check in the through storage door where the red arrow is for a removable partition directly behind the city hook-up fittings. Now if there isn't a removable partition there then look at the carpeted area beside the bed area above that point inside the bedroom for a seam in the carpet that looks like it is removable. Search with your fingers for sunken screws that will allow you to remove the cover.
