In the US, a retired bus driver couple converted an old American school bus into a full-time mobile home, a project known as a skoolie. The interior now features a fixed bed, kitchen counter, cabinets, and a compact bathroom. Conversions can cost from a few thousand to tens of thousands of dollars, roughly R$52,000 to R$261,000. Owners emphasize the need for proper insulation, ventilation, and compliance with state registration and parking rules.
