Can you drive a class A motor home from Bangor to Montreal? What are the roads like?
Yes, you can drive from Bangor to Montréal. If you want to drive right now, December 30th, you might find some roads with ice patches, but most of the roads are clear at the moment. Bear in mind that roads in Québec can be bumpy, but highway 27 in Maine is quite curvy, so it might be slow driving on both sides of the border. I assume you want to go through Coburn Gore. From there you take highway 161 to Woburn, highway 212 to Cookshire, Highway 253to East Angus, highway 112 to just east of Sherbrooke, then "Autoroute" (like an interstate) 610, then Autoroute 10 to Montréal.
Google Maps shows 289 miles with a driving time of 5 hours 52 minutes, which seems to be just right because of the curvy road from Skowegan to Coburn Gore.
