I'm no aerodynamic engineer but there is also a reason manufactures are going to the rounded front roof line. You get better airflow over the top, less drag when your towing. I doubt it would make a huge difference in your fuel mileage and wouldn't let it sway my decision if I found a floor plan that worked for me with the billboard front.
You're right, you are no aerodynamic engineer :W ... manufacturers who profile a trailer's front wall do so strictly for esthetics and marketing purposes, not because doing so improves airflow or reduces drag. If that
were the case fuel mileage
would improve but in reality it makes little difference at all. When towing any full height trailer with a normally aspirated gas engine vehicle we can all count on +/- 10 miles to the US gallon, a bit more if the trailer is particularly light, the roads relatively flat, and with little wind, somewhat less than that for larger, heavier trailers and when upgrades & wind are encountered. Believe otherwise, regardless of what manufacturer advertising may suggest, and you'll be sorely disappointed. :W
