My favorite YouTube channel I would watch on this topic is Chrome & Disco’s VanCity VanLife.

Vandwelling is a lifestyle of living full or part-time in a wide variety of vehicles, mainly window vans that have been modified with basic amenities like house batteries, a bed platform, some form of toilet, sink and storage space. Although the term can apply to living in other types of vehicles, it is mainly associated with vans because the word vandwelling is a portmanteau of the two words van and dwelling. Some vandwellers live this lifestyle by choice; seeking freedom, self-sufficiency and mobility without paying into conventional stationary housing. Vandwelling may be done using a campervan, recreational vehicle, travel trailer, or a mobile home. However, SUVs and larger station wagons can also be lived in.
