"Being in a van was like a pressure cooker on our relationship," said Levi. "Traveling for 16 months together was not always easy, but you're in it together and have to solve every problem together — that can be good, and it can be difficult."

After reaching Argentina and returning back, the couple decided to get married. They now live in Seattle, where they are setting up their own business — an Amazon sale platform for brands — and are planning their next adventure on the road.
