Very interesting, the more I read the more I learn. I would like to read more about this. Can you direct me to this information, and I would like to see an example of a trailer with a round nose. Thanks for your help.

This actually relates more to larger trailers like big RVs and a big selling point for sway control hitches. A CT is generally small enough and the TV is big enough to have enough force to overcome it.
I can't find my old physics book from too many moons ago. A V still has flat surfaces as opposed to curved. Even though they are on an angle the drag is higher. The angle of the V makes a difference too. In a high cross wind situation, the V creates variable flat surfaces, which creates variable forces pushing on the trailer. The higher coefficiency of a flat as opposed to a V can cause problems. Curved surfaces give a smoother path for wind to deflect around. A teardrop is actually a better design for aerodynamics than a CT.
I found some info with a combination of more than one site for you.
