The 2011 Prius boat-tail trailer illustrates the first condition.

By using the same curvature,top and bottom,it's a way to help prevent longitudinal vortices which have enormous drag.And it avoids the tight turn you mention which would trigger separation right there.

OK, thanks, I'll keep the sides and top curvature the same, and try the make the bottom curvature the same also, although it may be a little off, there's a lot going on down there. I'll probably remove the rear bumper to make the transition from the bottom a little cleaner.
