Height from ground to awning track on GC680

[Carryon Cali Camping]

Hi All - just prepping before we collect our new to us GC680 later this week. We will be getting some kind of drive away awning for longer stays. Can anybody tell me the height of the awning bead on the Thule wind out awning to the ground and/or what height range awning you have (if you have one!) Many thanks
