The Rotinoff GR7 was designed to be used as either a tank transporter or heavy haulage tractor, and was the first vehicle to haul a load of more than 200 tons on British roads. The Swis army became Rotinoff's biggest customer, while Sunters of Northallerton, England, the owners of the example shown here, were the only British buyers. The vehicle was powered by a Rolls-Royce 6 cylinder supercharged diesel engine, which gave 275 bhp at 1200 rpm.
