I was thinking the Cd for the Caravan was around 0.32.------------ Back in 1922,Kamm and Klemperer developed a "minivan" shape with Cd0.16,half of the Caravan's.--------------------- With a receiver-hitch type cargo box,you might be able to fashion a short boattail extension which would mimic what the Germans did.----------------- You might not get it to 0.16,but you might see in the neighborhood of 0.24,and you wouldn't have to cut into the roof or sides.Vans respond well to boattails and it might help you to get closer to your goal of 40.
