Hi,
I have been interested in teardrops for five or six years now, aways thought they would be too heavy to tow with the cars I have(small, worn out, four cylinder, 5 speed hatchbacks). I have built a couple skin on frame boats, that is where a frame is built out of thin strips of wood (1/8" x 1/2") which are all tied together then fabric is stretched over it tightly and painted or epoxied. Which ends up giving you a very lightweight yet enterprisingly strong boat. I am wondering if this technique "skin on frame" would possibly work for a teardrop. One thing about using skin on frame building is that you can build almost any shape you can imagine except concave. Let me know what you think.
