From experience, the optional solar vent from Cobra does not last long in the desert Southwest. The older Nicro 'Day and Night' vents were great, but the motor in the newer ones doesn't last long and isn't any sort of standard part.
I'm considering the Flettner TCX2. Industrial grade passive vent, with a lifetime warranty.

Wonder if the black vent is more UV resistant than the white one, like the wheel chocks from Cobra?
