Oceana DiSanti was a 19-year-old college student in Olympia, Wash., when she became a full-time RVer.

Intrigued with the RV lifestyle from an early age, she bought a 2003 Airstream Safari on eBay and started living in it while attending Evergreen State College.

But while full-time RVing proved to be an effective way to slash DiSanti’s living expenses in the pricey Puget Sound area, one of the more expensive real estate markets in the country, she still ended up paying $1,000 per month for an RV site.

So, DiSanti did her homework and eventually relocated to Phoenix, Ariz., last November, which she said is a much more affordable place to live, work and attend school while she pursues a degree in architecture.

DiSanti’s home base is Desert’s Edge RV Park in Phoenix, where she pays $620 a month for an RV site that also includes water and electricity.

“I called like 20 different places, and Desert’s Edge was the only place that would accept me,” said DiSanti, who is now a 24-year-old student at Arizona State University, noting that many of the RV parks in the Phoenix area are 55-and-over communities.

So far, however, DiSanti’s relocation strategy is paying off. Not only has she nearly sliced her RV site expenses in half by moving to Phoenix, but she’s found that food is also less expensive than in Washington as well.

But while DiSanti’s living situation is unique for a college student, the numbers of Millennials and other young people who are staying at Desert’s Edge is rapidly on the rise, according to Jimmy Watson, who owns Desert’s Edge with his brothers.

“I am seeing a shift in the demographics of the park,” he said, adding, “Fifty percent of my tenants at Desert’s Edge are under 55.”

Watson said his youngest RV site renters include husbands and wives, boyfriends and girlfriends, as well as students and other young people who have jobs but live full time in an RV. He added that he continually sees high numbers of Millennials and other young people coming to his park, even during the height of the winter season, when Phoenix is normally overrun with snowbirds.

“If I had to guess the median age, it’s probably 35 for permanent tenants,” Watson said, adding, “I have a lot of contractors. (Last winter) we had 70, 80 or 90 couples roll through as young as 19 or 20 to their late 20s or early 30s. I don’t know if affluent is the right word. but they are working to get their degrees. They are keeping their overhead down, and they want to be mobile.”

Watson says the rising cost of housing is prompting many Millennials to consider full-time RVing not only for its lifestyle benefits, but as a way to cut their living costs.

“Millennials are more mobile,” he said. “They are not buying a home because of student loan debt. They don’t want to be in an apartment because they don’t want to commit to a lease.”

They also don’t have to worry about getting roommates or deal with roommate issues, which they might have to face if they rented an apartment, condo or house, which are more expensive, explained Watson.

Ed Bridgman, who is developing an RV park outside of Mobile, Ala., is seeing the same phenomenon of Millennials with RVs renting sites at RV resorts in his area, many of whom are in their late 20s and early 30s.

In fact, Bridgman planned to break ground in August on Homestead RV Community, an RV park that will cater to snowbirds, as well as Millennials. He plans to equip his park with a fiber optic Wi-Fi system specifically with Millennials in mind. He expects his first campsites to be available early next year.

Meanwhile, at Desert’s Edge in Phoenix, Watson’s contractors include young traveling nurses, as well as young men working in the construction trade, people like 30-year-old Ramon Martinez, who works as painter and construction worker, while also handling various repair jobs.

Martinez, for his part, said he sees a lot of young people like himself who are enticed as much by the affordability of the RV lifestyle as by its practicality for people who live and work on jobs in various cities.

“We get a lot of people that come in that do power lines,” Martinez said. “They all buy fifth-wheels and they travel. You can just take your home wherever you want to go. If I have a job somewhere, I can unhook and go.”

But while he likes the freedom of being able to pick up and go wherever the jobs are, Martinez said he also likes the lifestyle that Desert’s Edge provides.

“It’s like a little oasis,” he said, noting that he not only enjoys the tranquility at Desert’s Edge, but its amenities, which include a heated swimming pool, a hot tub and a full gym.

Millennials also develop a certain fondness for RV parks and the people who run them, just like the empty nesters and snowbirds who adopt certain RV parks as their home.

“I choose (Desert’s Edge) because they accepted me, and I stayed because they are awesome,” DiSanti said.
