I'm gonna be rocking a white stealth E150 cargo van. What kind of roof vent makes the most sense ? What are the pros and cons of the different style roof vents ? <br><br>currently I'm eyeballing this one pretty hard: <br><br>http://www.trucknvans.com/CRL-6-Compact-Dome-Van-Roof-Vent-p/cb354.htm <br><br>but if it makes sense to have a "pop open hatch" style roof vent for some reason I'd love to hear why. <br><br>I have no way of knowing how loud the fan is on any of these vents. Money is no object for this because I want the best system possible. I'd love to hear any opinions <br><br><br>
