The bark does look like an older striped maple (Acer pensylvanicum) but usually they grow straight and not that big (they go to 10'' diam tops. Does the younger bark in the upper branches have a green tint to it? If so i'd say striped maple.
Get a picture of the winter buds if you can, it's hte best bet for identifying trees if they dont have flowers or leaves.
Hope it helps!
