Florida-based company It's All About Efficiency has introduced the Black Panther RV, which externally resembles a closed cargo trailer. The 4.8 m long, 2.6 m wide model has no windows for maximum privacy. Inside, the 12.5 m² space includes a sleeping area, living room, kitchen with a two-burner stove and refrigerator, and a bathroom with a separate shower and composting toilet. The starting price was $27,100, later raised to $39,000, comparable to the cost of a new compact SUV.
