I am saddened but not too surprised by the negative response here to what is really a positive and well balanced article and some of the comments about full timers.
A few points are in order I think:
Wikipedia is not accepted as a source for anything by any college or university in the US that I know of. Better the Oxford Dictionary of American English.
Some of the posts seem to belie the authors as being threatened by those of us who can full-time and be perfectly happy about it. There is a whiff of superiority adrift here.
If any of you have been around this country to any extent you could not help but notice the surge in people living full time in RV's and working normal jobs and staying in one place. At the cost of housing in some areas this seems to be a reasonable alternative to me. This is just RV's as alternative housing.
There are also a cohort of those who travel and live in their RV's full time and do "Temp" or distance work from a permanent employer or are self employed. (I know people who do this from their boats also) This is their choice and if it works for them what business is it of others to criticize?
Then there are the just "Full Timers" who follow some pattern of travel around the country, do not work and are able to support themselves just fine.
I think some posters here are just threatened by those who don't share their view of what is the "correct" way to live their lives.
