The selection procedure was won the Roudnické slévárny a strojírny (Foundries And Machine-Works of Roudnice) with its ROSS R210 project.

It intended to modernize the original project, and it also hoped that the Czech Army will finally undertake the replacement of its fleet of 4000 Praga V3s (while Tatra was supplying the Army with heavy trucks since World War I).

Tatra created alliance with other companies to work on the project together; for example the Praga was supposed to deliver gear boxes and portal axle.

[3] In 2005 the Czech government approved acquisition of the T810 trucks in August 2005, while deliveries were scheduled to start in April 2008.

[4] The civilian version T 810-C was introduced in 2010, with Tatra claiming it is the only truck with maximum weight of 15,5 tons that has three driven axles, which together with its portal architecture is supposed to give it advantage over the competition in terrain.
