LOS ANGELES >> For Heidi Hansing, the last three years felt as if she were moving backward.

“Nothing in my life was what it seemed,” Hansing says of her divorce after 22 years of marriage. “Everything had changed.”

For 30 years, Hansing had served others, beginning in the Army when she was 17. Later, she raised a family and served as a city council member in League City, Texas.

She was on the verge of becoming an empty nester.

“I didn’t want to rattle around my house like the half of a former whole,” Hansing says. “I thought, ‘What does Heidi want out of life?’ ”

Traveling was at the top of her list. She looked at where she wanted to be — traveling to the Blue Ridge Parkway in Virginia and North Carolina, Crater Lake in Oregon and Key West, Fla. — and “backwards planned” from there: She sold her four-bedroom dream home, made a commitment to living small, put her memorabilia in storage and bought a Living Vehicle from Santa Barbara, Calif.-­based architect Matthew Hofmann.

Hofmann was a popular vendor at the annual Dwell on Design trade show held in April in Los Angeles. Visitors were transfixed by the idea of sidestepping crippling real estate and rents, others dreamed of opting for a simpler life, or satisfying their wanderlust.

After updating more than 400 vintage Airstreams for clients and living in mobile spaces himself for a decade, Hofmann, 34, knew a lot about small-space living.

And in an age of housing shortages and skyrocketing home prices, Hofmann saw an opportunity to design a 21st-century mobile home that was less about recreation and more about function.

Starting around $149,995, the Living Vehicle is made of steel and aluminum and can be towed with a full-size pickup truck. (The LV travel series, starting at $90,000, will debut in fall). The custom vehicle can sleep six and comes equipped with modern amenities such as solar panels, Wi-Fi antenna, lithium batteries, an iOS operating system so it works with your iPhone, a spa-style shower and self-­supporting deck.

The interiors are intentionally light and bright with white walls, skylights and windows to avoid what Hofmann calls “a tin can vibe.” Looking ahead, he hopes to create a net-zero vehicle that requires no fuel or utilities to function.

One big consideration for buyers: Where to stash it, especially when you’re on the move?

Such vehicles are typically parked in an RV park or on personal property, but some municipalities may not be so welcoming. Such considerations need to be thought out in advance — and double­checked with local authorities. Hofmann advises customers to consult with the Bureau of Land Management’s website, which lists free campsites that can be used for up to 14 days. (Hawaii’s state park campgrounds are not equipped for camping in vehicles, including campers, vans and trailers. The sole exception is at Wai‘anapa­napa State Park on Maui, which has a small area designated for camper vans.)

Hofmann sold 15 vehicles in a span of three months and thinks the interest demonstrates a shift in how people want to live.

“There is a major shift now, especially among millennials — people are valuing experience and connection with other people over tangible things,” says Hofmann, who splits his time between a boat in the Santa Barbara harbor and traveling in the Living Vehicle with wife, Joanna, 30. “Millennials tell us, ‘I can be a homeowner.’ ”

The movable lifestyle clearly speaks to people, regardless of age.

Petaluma, Calif., residents Nicole and Yon Perullo, both 48, purchased their Living Vehicle while in the process of selling their home.

They had hoped to purchase another home, and use the Living Vehicle as an accessory dwelling unit, but couldn’t find housing after the Sonoma County fires in October 2017.

The couple did an about-face and are now renting a 200-acre property in Oregon with plenty of room for their Living Vehicle, pets and daughter Eily, 8, and twins Wyatt and Nathaniel, 10.

Nicole Perullo says they hope to use the Living Vehicle as an Airbnb in Oregon, and for family travel.

“I really want to travel with my children. I might take a year off and home­school them,” says Perullo. “We would like to go to Boulder. Or San Diego. Or to some of the state parks. I’m a stay-at-home mom. My husband is in finance. He can telecommute.”

This kind of versatility in homeownership, however, is not without a learning curve.

“It’s not easy being this free,” says Hansing, who runs a skin care line from her phone and has lived in her Living Vehicle full time since December. “It’s been humbling. I have to be knowledgeable about my trailer, which is super high-tech. It is hard manual work. I joined a Cross Fit gym to prepare for traveling on the road. My body is bruised and sore, my hands hurt from setting up camp, loading, hitching. It’s not glamorous. But when it’s done, I’ll pop a beer and think, ‘I deserve this.’ ”
