Ah, isn’t this what’s called a camper? Next, they’ll be glorifying tent life.
In my day (1976) you could buy a “mobile home” if you had a factory job. Bought a used one from a buddy to get his ex-girlfriend out for $2200 @19 yrs old. Yep, I was what is now called “trailer trash.” The next year, I bought a new ‘77 Pontiac Sunbird for $3600. I worked in a foundry as a caster’s helper.
