Duncan RV Service & Repair Elkhart IN to Camp Lord Willing RV Park Monroe MI 198 miles.  We started on back roads, IN-19 north becomes MI-209 at the Michigan line to US-12 east to M-40 north to M-60 east to US-131 north.  US-131 becomes a freeway just north of Schoolcraft MI to I-94 east to I-275 south to US-24 south to Stumpmeir Rd west to the park.  And that was our trip to our summer home base.
