Recommendations for New England route

[05monacoer]

Now in Burlington VT and headed for Bar Harbor. Currently planning to route I-89 to Montpelier, then 2 to St Johnsbury, then 93 to just beyond Littleton, then 302 and 115 back to the 2, then 219 to 95... up and over. Can any tell me whether the 2, 302, 115 and 219 are good big rig roads? Pretty sure that 2 and 302 are OK... not too sure about the 115 and 219?
Alternative is to stay on the 2 all the way to Bangor.
Also, planning to stay at Timberland Campground near Gorham NH (about half way). Alternatives are Stony Brook, Bethel Outdoor Adventures or Pleasant River, all near Bethel ME... Any recommendations among these?
Thanks NE'ers!

As a former "Maineiac", I can tell you that Rt. 2 is an "OK" road into Maine from where you are presently. There are some slow spots (small towns), but most of the road is easily drivable with a big rig. I might recommend Beaver Dam Campground in Berwick, Maine; it is located just over the state line (NH/ME). Also, the Pumpkin Patch RV Resort in Bangor (actually Hermon, ME) is a great RV destination, especially for big rigs. Bar Harbor will have some good and not so great campgrounds, but be forewarned, that many, if not all, campgrounds in and around central ME close October 15th. Have a great trip and enjoy the scenery!
