Hi, I am a newbie. My husband owns his own business and we may actually take Two weeks this year. Our plan is to travel from north central Ma. To mackinaw, Mi. We have a 21 ft microlite travel trailer and a new Ford F-150. I guess my main question in planning a route is how do I know if it is a route for a travel trailer verses just a car?. I have been looking around the site and didn't see anything to distinguish the routes?
