I have a single kitchen base cabinet that is about 28 inch across that I would like to have a drawer across the top. I plan to use a slide for the drawer. I planned for one drawer but now have concerns over it being a single drawer. There is an electric box in the rear side that makes 12 inches my limit on the depth. Help me decide the best way to approach this issue. If I make two drawers how would I add the support needed. Lorraine
