Reddit mentions of Carefree 902315WHT Awning Support

Carefree of Colorado.... makes a whole setup for this, and the idea is that even in the windy situations, you don't take it down.... you support the awning from underneath with this, and then run additional awning supports up under the awning like this, then hang the room. Then stake it down, and put in a mat or carpet on the inside and tuck the loose flaps under that mat. Many people run this setup through the deepest of winters, and use it as a Wet Room coming in from the cold. Reportedly it helps the heating bills on the inside since you are insulating that portion of the RV with an additional "warm" space, using the infrared heaters inside of this as well pumps up the values and livability.
