Since this is the UnAerodynamic topic. I wanted to ask a question related to this. It has been said on here that on most brick shaped vehicles that the rear is where you can get the most aero-benefit for MPG. So I attached two images of a large random un-aero brick shaped RV. I know a full boat tail would provide the MOST mpg gain over what I am proposing. But what if a smaller pyramid shaped tail was installed as opposed to a full boat tail. Do you think that a MPG gain would be noticed on this large brick shaped vehicle?

If so, what kind of gain do you think it would provide?

I'm asking this "what-if" question as I'm considering a similar replacement for the van that I sold. Thanks
