It's not my design, but I haven't seen anyone else do one lately... I'm going to take the basic shape of Wally Byam's 1935 Torpedo and scale it down to teardrop size. I've started on the frame, which was a Jayco pop-up measuring 76" wide and 80" long. The windows won't be the same, but the front curve, roof line and rear duck tail should be about the same. I might put a rear facing scoop on the roof for the A/C. I know that careful planning is a key to success, but I prefer not to think too far ahead on this project. We'll see how it turns out.
