Rusty roof chop

[rollercoaster]

I don't know if we are getting confused here,
the lower vents feed (?) the engine bay for cooling..
On my truck at least (syncro) the higher vents feed the cool air in,
through the closed chassis sections to the engine inlet.
That is on one side only, nothing doing on the other side.
I doubt wether air for the cooling could channel that way,
feels to me as though its as much for convection..
which is to mean cooling by hot air rising, (when stationary)
as anything else, and may also help generally.

There is a weird back pressure as you drive,
as anyone who has driven with back door open might know,
pushes air in forwards from the back and possibly out the side vents.
Which is why engine seal/door seals (on vans) are very important,
if you dont want to breath engine fumes.

All important considerations come to think of it,
in your thoughts, designs and finishing details.

As ever, happy to bow to anyones better understanding,
most of that is intuition or guesswork!

On the hot engine subject and pickup bed..
its often a bit of a struggle dealing with the heat.
I carry all sorts of loads and fairly often they dont want to get cooked.
Which they do, roasted, if placed on the rear half of the load bed.
Just in case that affects your thinking things through..

I know. Didn't want to admit it in public in case I was alone, but I think it nearly works.

I'm with aj, at looks neat. At first glance..

But then I start to get very concerned about how the heck the passengers are supposed to get in, and out...
