It looks like one possible route that might be flatter would be to go through London (Canada), but make sure you double check everything if you're planning a road trip.
Elevation data comes from different sources and may not reflect true
driving conditions, so talk to other RVers if you're concerned about
steep grades. If you're planning to drive in the winter and you want to avoid snow, check the road conditions from Detroit to New York City. You can also view a 3-D map of Detroit elevation or New York City elevation.
These are some of the possible highways along this route. Use the GPS in your car to verify all driving directions. If you're looking for campgrounds along the way, search for RV parks between Detroit and New York City.
