Having done most of your trip last year except mine was Cape Cod/ Old Orchard Beach/ Acadia/ White Mountains I can tell you there is waaaay too much driving in there. My trip mentioned above was 18 days long and we stayed at 4 different campgrounds. Cape Cod took 6 days by itself and I still feel I didn't see all of it. 1 day for Acadia is quite the injustice. Same for the White Mountains. No way you can get all that done in a day. We stayed at Lost River Valley Campground and it's an hour drive to the Cog. Half day for the Cog minimum.
