omnistore 4900

Does anyone have the Thule QuickFit Tent and use it on a SWB T6 (Thule Omnistore 4900)? I’m looking at this as an alternative to my large Vango Galli on short trips. My concern is that the QuickFit is too small for just a 2.6m awning and that the sliding side door on a SWB would not open far...
