I'm in the RV community, I live part of the year in my 5th wheel for work. I'm also 26 and do it by choice. I pile up my stache, have more freedom, always get to sleep in my own bed, no bed bugs or roaches, etc. There is a huge difference in people's perception when it is a choice vs when it is a necessity. On youtube there are two really good contrasting examples. Knorpp and South are a family of 12 or something like that, who lived in their RV by choice for cultural experiences and seem to be quite well off (now doing a Europe trip). Road Rice are a family of 9 who are quite poor and it is not really a choice, it's all they can afford. The latter channel are much more likely to have negative comments. In one video they even filmed CPS being called on them, from a youtube viewer!!
A lot of seniors have not saved enough money, and SSI is not cutting it when they have a large portion going to rent/housing. Sometimes living in a car/van/RV is all they can afford. But in a way it is a choice. They can either be homeless on the street, in section 8, in a stationary trailer park, or they can travel in a car/RV and get part time traveling work. The RV community is actually quite friendly, it seems that the people in sticks and bricks are the ones who are mean and don't want to be around anyone who is poor, like it's some sort of catching disease. I think the main fear is that poverty is associated with drugs, alcohol, uncleanliness, stealing, etc. But honestly I have not seen that in the RV/workamping community. It's mostly nice, retired people.
I have a career, good degrees, etc and I have considered Workamping, seasonal work at national parks etc, as a choice once I'm FI. We'll see how it goes once I'm closer!
