10 2026 GT 1 Series Awnings, Vents, and Doors

Awning:

The Girard Systems power awning (Figure 10-1) comes standard on the TIFFIN GT Series, providing users with a reliable and convenient outdoor shade solution. Engineered for durability and ease of use, this awning enhances outdoor comfort by offering protection from the sun and light weather conditions.
Designed to withstand light rain and mild wind, the awning can be safely deployed under these conditions to enhance usability and enjoyment. However, if strong winds or heavy rain are expected, or if the awning will be left unattended for an extended period, it is highly recommended to retract it to prevent potential damage. Inclement weather can place excessive stress on the awning’s structure, leading to unnecessary wear or failure.
To ensure longevity and maintain optimal performance, users should follow proper operation guidelines and regularly inspect the awning for signs of wear and tear. Please note: any damage resulting from wind or rain is not covered under warranty, so taking precautionary measures to protect the awning is essential for maintaining its condition over time.
