Anyone ever come across any aerodynamic info or studies on the first gens?

If you search on Dodge Dakota mid-sized pickup trucks, 1987-1996 | Allpar Forums - about 75% to 80% down, you'll find the 1st Gen drag coefficients.

For rear wheel drive, ground clearance was at least 6.5 inches for all models, with a 28.5° approach angle; the ramp breakover angle went from 13.1° for the club cab to 15.8° for the short-box regular cab. The drag coefficient was 0.49 for the short box regular cab (other models were within .01 of that), little emphasis having been put on aerodynamics. Frontal area was 25.23 square feet.

For 4x4 models, wind resistance was higher, with the drag coefficient at .56 (except club cab, where it was .52). Ground clearance was 6.3 inches on regular cab, 6.9 inches on club cab. Approach angle was at least 35.2° on regular cab; breakover angle and departure angles were 15.7 for the short-box regular cab and 13.8° for the long-box regular cab. Frontal area was 25.84 square feet.

That’s partly what I was looking for but for a Durango.

So I’m building a Durango to travel around the country in pulling a mid size travel trailer. Or maybe some trips just tenting. I would like to ad a heat extraction vent on the hood to aid in flow through the radiator and decrease drag. I was wondering if there were any wind tunnel edifies or computer simulations of airflow over the hood and where it would be most effective.

Well, you didn't state, so I used first gen Dakota ...

I have no idea.

Check out Allpar's articles on the Durango?
