Choosing between the 90 degree awning and the 270 degree awning depends on your specific needs. The OPENROAD 90 degree awning is ideal for smaller spaces and provides targeted shade and protection from sun or rain. Compared to the OPENROAD 270 degree awning, the 90-degree awning is easier to install, with a quick and simple setup that you can complete in just one minute.The 270 degree awning, on the other hand, offers much broader coverage, wrapping around the side and rear of your vehicle. It’s perfect for larger campsites or when you need to protect more gear and space. If your needs are limited to shading one side of your vehicle, the OPENROAD 90 degree awning might be the better side awning choice, offering effective side protection while being easier to install and pack away.However, if you require a wider coverage area, the OPENROAD 270 degree awning is the recommended choice. Its expansive design provides superior protection, making it the best option for those who want maximum versatility and coverage.
