I don't really like the fully enclosed horse trailers. I think they are unneccesary for a horses comfortin the winter and can quickly become too hot in the summer. I prefer stock tailers. If I am hauling in the winter I put the saddle on before I leave or if I'm going a long ways I might throw a blanket on before starting out. In the summer they get plenty of airflow and if I need to reach in for some reason there is alot more access. When it is raining and you are going down the road the slipstream going past your trailer keeps most of the water or snow out and the horses still stay pretty dry.
