Jeremy Corbett's brother Greg hits the road in a caravan

Right now, it's the middle of winter, and many of us are dreaming about a Kiwi caravan summer.

But what if it wasn't just a summer holiday? What if you ditched the nine-to-five, sold the house, and upgraded to life on the road?

Many have done just that.

Forget tiny homes, it's all about travelling homes; living off the grid in a bus, caravan or motorhome in one of the best places on earth. That kind of sweet life is something the whole world should see.

Luckily, many of these nomadic New Zealanders have answered the call and share their journeys online; like Palmerston North native, and brother of The Project's Jeremy Corbett, Greg and his wife Sandy.

Last year, Sandy was diagnosed with a blood cancer and told she only had four years to live.

Following the life-altering news, she and her hubby sold their three-bedroom home, bought a Jayco Silverline touring caravan, and started their adventure.

"The hardest part was downsizing," Greg told The Project. "We had to get 20 years' worth of stuff into a 24-foot caravan."

Sandy agreed. "Yeah, we had a lot of stuff." 

Of course, that means some of their treasured items had to go. But they're not forgotten.

"With a lot of our special things, we took photos of them," Sandy said. "If we do miss something, we can just look at a photo of it."

First, they travelled around the North Island - hitting places like the Coromandel, Hamilton, Wellington, Tauranga and Thames - before heading to the South Island. Along the way, Greg and Sandy have shared their on-the-road adventures on their YouTube channel, Kiwi Wanderers.

They admit the vagabond life may not be for everyone.

"You have to be good at living in a small space. It took us a little while to get used to our spacial awareness," Sandy told The Project. "We just kept crashing into each other for a while."

Along the way, they've had some very good news. After chemotherapy and radiation therapy, Sandy's prognosis is much better.

"At the moment, everything is all good," Sandy said, snuggling closer to Greg. "I put it down to living the relaxed lifestyle and living with this guy."

The couple has no plans to leave this life on the road. Sure, if they fire up the microwave and the coffee machine at the same time it's lights out, but they're loving all the time they spend together. And they've many other tourists along the way.

"We're not tourists, we're explorers," Greg explained.

Ah, sorry. The people these lovely explorers have met on the road have all been friendly, fun, and helpful.

Still, it's a big change from their old dream home in Palmerston North. 

So, do they miss living in a house? Or, maybe, just one that doesn't have wheels?

"Not missing the house at all," Sandy told The Project. "Not missing the housework that's for sure!"
