There is something unforgettable about setting off on a motorhome adventure across the northern United States. This 18-day journey from Billings to Chicago weaves together the rugged canyons of the West, the sweeping prairies of the heartland, and the vibrant culture of the Midwest. Covering 2,193 mi, this itinerary is perfectly paced for slow travel, allowing you to truly immerse yourself in the changing landscapes.
RV travel makes it incredibly easy to pause for family-friendly attractions, spontaneous scenic detours, and relaxing evenings at well-equipped campgrounds. With your accommodation traveling with you, you have the flexibility to wake up near ancient caves, spend the afternoon watching wildlife, and fall asleep under the vast skies of the Badlands. It is a family experience filled with natural wonders, cultural gems, and plenty of delicious food along the way.
To make the most of this cross-country expedition, we recommend breaking the 2,193 mi drive into distinct regional stages. Rather than rushing from point to point, focusing on regional rhythms ensures you spend less time behind the wheel and more time exploring.

This route is exceptionally diverse, offering a rich tapestry of experiences across six states. Here is a look at the types of activities you can expect to enjoy along the way:
Nature lovers will find endless opportunities to connect with the environment. The route features incredible wildlife watching, stunning botanical gardens, and mysterious caves waiting to be explored. Active travelers can stretch their legs in expansive hiking areas, go horseback riding, or cool off with swimming and canoeing, kayaking, or rafting adventures on the region's many waterways.
If you are traveling with children, this itinerary is packed with family activities. From awe-inspiring aquariums and science sites to extreme activities that get the adrenaline pumping, there is never a dull moment. You might even find yourselves embarking on a scenic sailing excursion or a cruise terminal visit as you near the Great Lakes.
Beyond the natural beauty, this journey is a deep dive into American heritage. You will encounter historical sites, art galleries, and museums that tell the story of the regions you pass through. Take time to learn about local industry, stroll through traditional markets, and treat yourself to fine dining or a traditional restaurant visit to sample regional specialties. For a bit of relaxation after a long drive, you can even seek out a local spa or thermal bath.
We strongly recommend dedicating the full 18 days to this journey. Covering 2,193 mi over nearly three weeks allows you to average a comfortable driving distance each day, leaving plenty of time for spontaneous stops, long hikes, and relaxed evenings at the campground.
Absolutely. The transition from the mountainous West through the Badlands and into the lush, lake-filled Midwest offers a masterclass in American geography. It is one of the most visually rewarding road trips you can take in a motorhome.
This route is ideal for families, couples, and groups of friends who appreciate a mix of outdoor adventure and cultural exploration. Because the roads are generally wide and well-maintained, it is also highly approachable for first-time RV renters.
Late spring to early fall is the optimal window. The northern states along this route experience harsh winters, so traveling between May and September ensures open campground facilities, accessible hiking trails, and pleasant driving conditions.
When planning a one-way trip from Billings to Chicago, there are a few logistical factors to keep in mind. First, you will likely incur a one-way drop fee, which is standard for rentals that do not return to their origin. Second, pay close attention to your mileage package. Because the base distance is 2,193 mi—and you will undoubtedly add miles for detours and exploring—you will want to secure an ample mileage allowance or an unlimited mileage package.
Your budget will also depend on the type of RV you select, whether it is a nimble Class B campervan for a couple or a spacious Class C motorhome for a family. Campground costs will vary based on whether you prefer the rustic charm of state parks or the full hookups and amenities of private RV resorts.
