Motorhomes with an overcab (a raised section above the driver's cab) are gaining popularity among families and large groups. This design provides two permanent sleeping berths measuring at least 2 m in length and 1.5 m in width without sacrificing living space. However, the protruding profile increases highway fuel consumption by 2–3 liters, and a height exceeding 3.3 m requires specialized navigation. Most models weigh over 3.5 tons, necessitating a category C license and posing higher risks in crosswinds.
