This teardrop has a large shade shelter up as well as a few added walls made from tarps. Having an outdoor rug also helps to keep the wet and mud from creeping into your trailer.
This trailer also has walls with some added windows for keeping and eye out for the sunshine.
This teardrop/standy is completely covered by a shelter. This might be necessary if your trailer leaks in any way.
It sometimes helps to rely on your neighbors for protection. Grouping trailers together, and forming a wall, can help protect from wind and rain.
