The previous winter had been a struggle to keep the trailer from getting waterlogged and ruined. Rather than deal with these issues, a tarp shed was built over the trailer. While not entirely pretty, it did a very adequate job of keeping everything mostly dry. It was the wind blowing the rain that was less than welcome.
Nonetheless, as soon as temps were warm enough again, gluing and caulking could commence. The luaun ceiling was laid over the walls and the spars and insulation added. The hole for the vent was also added. Given the curve of the roof, a standoff similar to house skylights will be added. The vent came in all white plastic. A full dis-assembly and shot of hammered spray paint should help it to blend in with the trailer.
