DH and I completed a NE trip in Oct, stopping in each of the states you mention. I put reviews of all the parks where we stayed on rvparksreview.com and recommend you look there for some suggestions depending on where in each state you'll be stopping. I can tell you there are not that many RV parks in western MA, however, we found a really nice, family friendly one outside Dalton. Of course, Norman Farms in Foxsboro is a must stay that is convenient for a drive to Patriots stadium, Boston, the Cape, etc. Che k out my review of the cg's we stayed at in ME (close to LL bean), NH White Mtns, and VT. Enjoy your trip...I know we had a blast!
