All words I have heard to describe the time reference of the RV Life style. I'm sure there are more ways to describe the way in which to approach the amount of time we spend on the road. My definitions may be different than yours. I believe the details of the definition matter little.
What matters most is for each individual or family to define a way that makes sense for them the life they want to live, so that the plans and 'home' decisions made will match their definitions and their preferences.
Working Definitions as a Starting Point
Some of the considerations I pondered were based on finances, desire to live more simply, and freedom from long distance maintenance and changing life responsibilities and commitments. Whether I choose long-term travel, financially I needed to downsize and change where and how I lived.
Another consideration worthy of consideration is the need for security. Does you home on wheels fulfill your need for home and provide a sense of security. Or is it provided in another place that you must return to in times of stress. The real test for me was the first time I became ill for more than a few hours. Could I wait out pneumonia, while hacking and coughing for weeks in a tiny space?
The answer for me comes with having a short-term Plan B. What will I do if..... There may be times that I need to land for a time do to illness, vehicle repairs, family need, (who can truly anticipate every possibility). My Plan B entails ensuring that I always have enough money in the bank to cover an extended stay in a base camp complete with electricity and water when I need life to be simplified.
