L’Automobile Magazine tested a TentBox roof tent in its special issue "Rouler différent, spécial vans." The device mounts on a vehicle roof rack and unfolds into a sleeping area with an integrated mattress, storage pockets, and ventilation. The standard version sleeps two, with a four-person option available. Installation requires two people due to the 60 kg weight. Driving with the tent causes aerodynamic noise from 80 km/h, increased fuel consumption, and a recommended speed limit of 110 km/h. Prices start at €1,000 for a two-person model and exceed €2,000 for a four-person version, making it cheaper than a motorhome or camper van but more expensive than a ground tent. The added height may prevent entry into low-clearance parking garages and toll booths.
