You could try tacking...

Moving on:

orange4boy,
You DID save all your measurements/templates/plans, right? I think you may have something here with the ability to produce an aeromod package for other Previa owners-- maybe just the plans alone, or complete kits. One aeromodded Previa saves your tiny corner of the Earth-- 10 of them save ten tiny corners of the Earth (the Earth has a plethora of corners).

If you are referring to the slope of the kamm, I did tuft testing with a chaser car (sorry no video) It looks steeper in the pic partly because of lens distortion and partly because you are seeing some of the side taper at that angle. I think it's ~12-14 degrees. What I really need to do is finish the lower sides and bottom and close off the end. I have too much work to do at the moment to be doing a lot of ecomodding.

I could pull some templates if asked. The attachment brackets are a PITA to fabricate but not impossible if you have some skill with sheet metal. Unless people see this as a custom green MPG mod, not so much a money saving mod then It might sell. It probably would pay for itself over time tho.
