Hey guys, it has been a LONG time since my last post.

I am currently building a 4x4 Astro camper van, but my inner ecomodder keeps showing through. the van now has a 6.0 LS with a 6l90 for double overdrive as well as a partial camper conversion.

I have been wanting to buy a high top (from a junk yard) but I'm not sure i can stomach the fuel economy hit with how awful most high tops are. I really want to keep the thing getting over 20mph hwy. (goal of 25mpg @60mph)

So, the logical idea is to build a high top in the Foamy style following the aerodynamic template.

Which of theses 3 do you think will work best? all 3 have been set to the exact same height (13" higher than the factory roofline) Assuming frontal area is the same between all 3.
