Currently, the couple is parked permanently in Dallas, Texas, so they don't have to budget for travel.
"I think the average rent for a one-bedroom apartment would be about $1,800, and that doesn't include utilities," Keely said of the cost of living in the Dallas area. "But we only pay $600 a month to rent out our space."
They have an additional $100 monthly expense in utilities, but they're still only paying a fraction of the cost they would for an apartment or home.
"We still are just as happy," she said of living in a smaller space. "We have everything we need, and we get to just kind of pick up and move wherever we want for a fraction of the price."
