Our first RV trip several years ago was to Acadia National Park in Maine. Our GPS led us onto a no-truck parkway with low bridges, so after a terrifying few minutes, we took the first exit and attempted to find a detour. This time my husband is driving alone from Northern Virginia to Bangor, Maine, as I have to work and will join him by plane. Do you have suggestions on the best route to take? I won't be able to help navigate. He prefers fewer tolls and less stress. I would appreciate any suggestions you have.
