A 2013 Range Rover was able to tow an Airstream 684 Series 2 from English Lake District to Morocco.
For this adventure Land Rover selected the Autobiography variant fitted with the SDV8 engine producing 339 HP (249 kW) and 700 Nm (516 lb-ft) of torque. The aluminum travel trailer was hitched to the SUV's electrically deployable tow bar and was transported from Airstream's European home in the English Lake District to the Atlas Mountains in Morocco and back.
In 11 days the Range Rover towed the 2,399 kg (5,289 lbs) Airstream for 3,676 miles (5,916 km) on just about any type of terrain possible. The SUV was driven for at least 12 hours every day during the trip, from Spain's empty motorways to the difficult hairpins of the High Atlas.
