Probably will be hard to find one same color. The covers are available at just about any RV parts supplier online, Atwood or Suburban, and usually available in white or black. Maybe almond, can't remember. If I were in your shoes, I'd probably just go back with the black color cover, but I don't know exactly what yours looks like on that side.

At least in Heaven, RVs will be perfect, and I won't have to keep fixing them.
