The shroud is a separate piece of fiberglass fitted to the area for reinforcement. However with the newer molds the roof is reinforced, thus no additional shroud is needed. My 2012 Escape 19 had the shroud, my 2014 21' does not. I know the 21' do not need them, not sure if the 19 is built like the 21 or may still need the shroud for a/c.
never in doubt, often wrong
