My thread is a bit tongue-in-cheek but I started thinking about all the difficulties that everyone seems to have when building the teardrop and a lot of it seems to be around the curved roof. Is it sexy? Definitely. Is it more attractive than a non curved roof? You bet your sweet bippy. Does it add and cause a lot of frustration? I think so. I guess it might save a few miles per gallon because it's more aerodynamic but I'm honestly considering not having a curved roof. Please see my highly artistic and scientific drawing.
Depending on the slope of the curve it seems like you do get more space inside as opposed to my design and I would have to reconfigure how to open up to the galley but it's a thought....
