Finished my Cubby last month to the point where I could start using it. It took three months to build, averaging about four hours a day. The Kuffel Creek instructions were a big help, and well worth the price. During Spring and Summer, I go windsufing two to three days a week in the Columbia River Gorge, and rather than driving back and forth to Portland each day, I park the teardrop at my favorite campground and sleep there.
It attracts lots of attention at the campground, people are always coming up and asking questions about it.
