An expando (or tip-out) is additional living space that slides out (or is tipped out) from the main living area. It is not necessarily of the same quality as the main section to which it is attached. Expandos are generally 8’ wide and 10’ to 14’ long. Tip-outs are generally 4’ x 10’ or 12’ in size. Enter the size of the expando or tip-out in square feet.
