Hi Charlie,

I am not sure about Ford, but the Chev cab vents had round funnels behind the mesh, not the square ones you see in the pictures.

Some of the pics you posted clearly show that the trucks are non-vent cabs, so presumably cab 11, as there are no holes visible in the front of the wheelwell panels....so I presume that's the reason the crew, or a workshop, added extra hoses and the square intakes. However....I do wonder why they didn't just cut a hole in the front panels.........unless they wanted to "aim" the are to their feet in stead of their legs (?)

The factory air vent hoses by the way are very short sections, so it looks the desert guys sourced the hose from somewhere else.
