I will check out the blade issue. Edit: I didn't realize that the fan had this style of blade. I will stick to exhaust mode, as generally speaking with the appropriate window opened this is more effective than intake, all other things being equal.A couple things that might be going on here...
- The MaxxFan has asymmetric blades which don't produce the strong downdraft you may be expecting, but the blades can be flipped to do so:

- Negative/positive air pressure. Have you tried opening the a door or window with the fan running to see if subjective performance improves? If so, consider an openable window or floor vent so the fan is not attempting to pull a vacuum or pressurize the space inside the van.
I am aware that a fan wont do well trying to pull air out of (or push it into) a sealed volume. With the rear door open I get the "best" airflow, however the speed with which this fan evacuates the hot air from the van is drastically less than other more pedestrian fans I have used. In my E-series I could open one rear door window and crank the fan up and the van would be ambient temperature inside of two minutes.
