What about cabin air intake filter also i guess?
Cabin air? Do you plan to keep this truck as a normal roadgoing truck the rest of the year?
I have observed that it is difficult to see out of windshield on the Playa, specally at night. A little of dust, and lots of other lights, and all you see is reflections. So if I was to do this, I would consider making the windshield removable.
