We have a 2009 Cruiser 29ck. I was able to drill a hole below the outlet the same size as a computer desk cable entery connecter. The extension cord is passed through the hole and the compartment door can remain closed or open as required. When not in used the plastic cable entery connector has a cover on it that can be slide into place covering the opening. These can be bought at most places that sell computer accessories. ( Wall Mart, Best Buy, Staples, Lowes, etc)
