I too live in MA and I use Costco when home and refilling. When on the road, I have a book called Next Exit and it tells what is at each and every exit on highways so you know where the truck/RV ready stations are. On byways it is harder, I was in Vermont and pulled into a station that the roof over the pumps was about 12'8" and I was 12'6" pretty scary but needed the bathroom and needed fuel (diesel with the truck I was pulling a fifthwheel with). WATCH your heights of overhangs and such and watch how much space you have to pull o ut and not take the tank with your or the sidewalk/front window of the station. Safe travels!! Costco never gives me problems. Also there is a truckstop just off 95 near 495, not sure if you are near there.
