People are starting to embrace a portable or nomadic lifestyle. There are full time RVers, Van Life people, even a lot of homes in the Tiny House movement are capable of being moved.
There are a lot of good reasons for this. Between low wages, high college dept and higher prices on everything, the best way to live could be small footprint. Granted, some of the RV's and Tiny Houses can be as much as a regular house, but there are other, less expensive options.
You can use search tools to locate used RV's for sale. Be very sure to check them over, there are stories about them not being particularly well built.
You can build your own Tiny House. Search out articles and videos about people who did it themselves.
Besides traveling, and the cost of ownership, there is another important reason to consider a portable lifestyle.
If your home can move, it can be moved out of a danger from natural or man-made disasters. Lose a job? If you own your home and it is portable, go to where you have a better chance of finding a new job. Better yet, try for a remote job that will allow you to work at home. In this transition age, we have some idea of places that may be safer than others for the worst results of climate change. Being mobile means you can search for a place that may be safer, and where you may be more comfortable. A better fit.
As being prepared is a central theme to this site, while you are planning and saving, you can still be striving to be prepared.
I strongly advocate for camping. You learn important skills that can apply to living a portable lifestyle. It is like a rehearsal, allowing you to experience moving someplace else and living there for a short time. Learn from mistakes, evaluate, tweak things and try again.
Not just skills, you will be acquiring equipment to be able to live more comfortably. Stove, heater, sleeping bags, tent, lights, and how to use them.
In a situation, even if you don't have a portable home, you have the parts to go away and find a place to live, even if it is a more simple existence.
All of those parts can also be used at home, or added to your new portable lifestyle.
Storm or earthquake, snowed in or unable to pay for utilities? You have equipment that you can use at home just as easily as camping. Cook your meals, stay warm, have light.
In a multiple state black out in the middle of summer, you house could be the only one that is functioning, even if simply.
Going beyond camping, learning some Survival skills and knowledge may provide a substantial boost of confidence in being able to go anywhere, live anywhere.
I'm not talking about running out and buying a gun. Although some way to defend yourself, your family, and your property is something you should continue.
What I am referring to is how to address your needs. The rule of three.
In general, the human can survive for:
3 minutes without breathing (asphyxiation, blood loss)
3 hours without shelter in an extreme environment (exposure)
3 days without water (dehydration)
3 weeks without food (starvation)
You can find classes, or check out You Tube or the Internet.
Hands on experience will always beat out book knowledge, but book knowledge will more often than not be better than no knowledge.
It has been said that someone who knows how to survive is truly free, they don't need to depend on any system to dictate and control them.
