The black material you are referring to is coroplast and is "supposed" to help keep the underbelly and its contents - tanks, pipes, etc. - protected from the winter elements and to protect the "underbelly". In a way it is part of the "Polar Package" - essentially an advertising gimmick used by Keystone and others to give the impression that these units can withstand long periods of freezing temperatures and that you will be warm and cozy while camping. For your situation, forget about the Polar Package and try to plug as many openings as you can in the coroplast.
