Our Trucks Work Harder so you Don’t have to

The Monterra family of extreme-duty trucks are the most capable and versatile chassis in the North American truck market today.

Thousands of organizations require unfettered access to torturous worksites where other trucks simply cannot perform or survive. The Monterra was born from the need for an extreme-duty service truck that reliably performs, for decades to come.  With unmatched versatility, the Monterra can  accommodate an endless variety of service bodies suited to a broad range of configurations for mining, pipeline construction, oil and gas, utility, border protection, wildland firefighting environment, or any other extreme terrain application.

The Monterra 6x6 is also available in a Tractor model allowing for easy hauling in and over virtually any worksite.

No other vehicle defines value like the Monterra – providing a one of a kind elite work truck at a significantly lower price than any competitor.
