I would make some of those longer weekend rides fully loaded rides. Preferably, they should be things like overnight trips. Ride 75 miles to a campground and then ride back the next day. But if that is not possible, at least ride the bike loaded for 75 miles to get a feel of what to expect on a 75 mile day. And with your timing, you might consider reservations in Acadia if you plan to camp there.
