Your shore power enters the wall behind your sink cabinet. If you remove the right side false panel under your sink, you will see the backside of the shore power connector and 10/2 romex that feeds your power center. There is room here, but there is a lot of plumbing in this location, so I'd choose elsewhere. The cable should run aft, behind the drawers and range to the power center. Behind the power center is probably the best location, but there might be room behind the drawers too. Make sure to get a remote display or a model with bluetooth, as none of these locations will be visible.
