Sunroof/moon roofs are reported to be problematic in vans, eventually leaking. Many here have done the fansastic fan or Maxx Air installs in their roofs without issue, but rain can still be an issue.
I use a mushroom vent on my roof and use 2 counter rotating variable speed computer fans to exhaust air, but these can only move ~150CFM max But there is no worries about rain. The fantastik fans can move something like 800CFM on high speed, and require a 14 inch square cutout.
Sometimes I think a lower profile vent like used on boats and with a few computer fans on a removable shroud, inside of it, would work pretty well and not stick up as far:

hard to beat a fantastik fan though.
Heres something similar to my roof vent:

I wound up ripping out the electric motor and battery guts and just using 120MM computer fans attached to a step down ring, 4.75 to 4.0" for 10x the airflow. But redoing it today i would use a larger mushroom vent and larger fan.

Proper ventilation is in my opinion, pretty important to living comfortably in a van. I like being able to control the speed/noise, and amp draw of my many computer fans. I have 3 intaks fans in a conversion van slider window, but it seriously has to be HOT for me to turn on all three at top speed. the roof exhaust fans are often cranked upto the maximum. Their white noise also helps me sleep thought loud environments, I often crank up a fan just to drown out other noises, not even for the airflow factor.
