The degree of rounding the front needs is actually quite small. A radius equal 4% of the width has been mentioned before. That's a 4" radius on a 100" wide vehicle. Just need to get the air to flow smoothly to the sides and top.

Add some rear taper and you're about as good as you can get. Look at a Monaco Vesta, or Vixen motorhome. Both were designed in a wind tunnel. The Vesta had LOTS of resources behind it, way more than you have I assume, and it really doesn't have an unusual shape or features. You probably shouldn't either.

Oh yeah. Slow down.
