Hi everyone! Any additional thoughts welcome!
I think you did a pretty good job of delineating the issues of a V nose trailer. Two things I would add. How much compromise inside the trailer will the V nose create and can you live with it? And, where I live the wind blows all the time (almost) and to tow with a V nose there will almost always be a frontal area that the wind is hitting unless the wind is from the rear. So, for me a V nose is not in the cards.
In a no wind situation rolling resistance is more important than wind resistance up to around 40-45 miles per hour. The time spent over 40-45 mph is when wind resistance becomes important. So, the nose shape is not that much of an issue under 40-45 mph.
