I wouldn't remove it. I think it would be impossible to remove by oneself without tearing something up, bending something, or otherwise causing more problems than it would solve. I had mine professionally removed on a unit I used to own. It took two technicians better than three hours to remove it in pieces. The rubber rope-like piece that holds the awning material in the awning channel is a real bear to get out due to dirt and corrosion that accumulate over time. That's a MAJOR undertaking for little, if any, benefit. Leave your awning alone.
If possible, storage of your trailer under a shed or in a building would help protect not only the awning, but the plasticoat finish of your aluminum shell, the rubber beltline parts, painted areas, vent covers, air conditioner shroud and your tires. I'm fortunate. I ranch and I have a number of barns, several of which will accommodate our trailer. You should be able to locate a farmer, rancher or someone in your area who would allow you to store your trailer in the off season for a very realistic cost that would be much cheaper than paying for a storage unit in a storage facility. Such an arrangement would help not only benefit you, but the farmer or rancher as well. The only time our unit is not in storage is when it is being used. Our 1982 still looks new after all these years due to our keeping it out of the sun and weather.
