This is the cockpit, and I think that might be an air tube for the driver to be able to breathe some clean air instead of dirt and mud- though I could be completely wrong.
As the front of these trucks often are covered in dirt and mud, the radiators are mounted back here with the four fans to pull air through them.
And more fans and radiators… And the fuel cell in a safe place.
This vehicle is built for a different type of off-roading, the King of the Hammers race.
I love how beefy the suspension components are and the fact the remote reservoir requires external fins for cooling.
Beefy heim joints are used everywhere and allow for the articulation.
