Tonke Explorer

Extreme comfort even in the most remote areas

The Tonke Explorer is an expedition vehicle, based on the Mercedes Sprinter 516Cdi with 4×4 and a hi/low gear box (standard). Optionally this vehicle is also available as a 6×6 based on the Oberaigner conversion of the Mercedes Sprinter (see pictures). Thanks to the rigid Sprinter chassis the Explorer has excellent off-the-road properties and still have a passage to the driver cabin. This combination is rare, because most terrain trucks have flexible chassis that make a pass-through impossible (the car would break). The main advantage of a pass-through is efficient use of living space in relatively short lenght and the possibility to take passengers in a comfortable way. The Explorer in standard equipped for 4 perspons.
