I like idea of chicken coop or barn vent on roof of Van to remove hot
air.
Don't you think it would be loud ?
They make big noise when spinning, no bearings.
How high off roof should be to work good?

Good Morning,

OK here we go again!
I worked for Triangle Engineering in 1975 as a marketing manager.
Triangle engineering was, at the time the worlds largest manufacturer of
Roof Top Turbine Ventilators.
After exhaustive testing at Texas A&M university with about ten
varieties of ventilators that were designed to suck.
None of them sucked, they all drafted exactly in proportion to the size
of the hole in the roof.
Since heat rises and the wind blows when it rains it makes them twirl.
Its apparent to me that we need a twirling scoop. That way it would
perform exactly like the hole it covers.
All of you folks have seen my half assed wind ram at
http://williamwareagency.com/forsale/stanvan/vent.htm Now this thing
blows your sun glasses off at 60 mph as well as dehydrating any fruit
you happen to have in the van. So a ram vent is a real help if you stick
an oil cooler behind it. Granted you're going to get a fair amount of
dirt, insects, rain in your cooler and in your engine compartment but
wow! its great to be cool. Not me bubba, I just stop and turn it around
facing backwards and it becomes an exhaust vent on rainy days.

exhaust fan in the rear and ground touching skirts on your damned vans

scoops
because they don't suck in the looks department though they suck in the
function department.
