I'm so glad to have found this forum to see other's ideas and trailers.
Currently in the design phase of my travel trailer, although not a tear drop, I want it to be as small as possible but still provide comfortable accommodations for two adults including a nice dry shower. All aluminum v-nose with high clearance for mild off road or unimproved road travel. Other key design features are no roof penetrations, fresh and gray water tanks installed inside trailer and sub-floor for all wiring and plumbing installation under removable floor panels.
Looking forward to exploring this forum and sharing my design for others to provide suggestions and comments soon.
