So that's basically the same as the ToyoAce truck.

Hi guys, this is my truck camper.

This is the before photo, with air not directed into the radiator, which is tucked up inside the engine bay. There are steering rod linkages and pipes in front of the radiator. most air goes under the truck, bypassing the radiator.

Yes an early version of the toyoace/dyna truck. I've looked at many small truck designs, and even 1995-2010 ones i've looked underneath at don't seem to pay any attention to the airflow underneath the vehicle, or radiator flow!

It took a while to parse out but...

3 years late, but I've been working on improving the aerodynamics of my hiace van, the starting point of my van is worse than a townace...

...it wasn't clear that you're not the OP (who hasn't posted since 2016).

You can direct message the mods and they will spin off a new thread for you if you want to become the topic. That said, how does it compare to the Previa? And what's with the transfer case on kach22i's example:

I guess mine is what you call a cab forward van, with cab over the engine, a previa is a people mover but a much more modern van.
