Re opening stuff under the awning, cant open the window, if you do you will find you cant open all the way out to shut the blessed thing!!! we just open all the others. can open the under locker fine though, and have a Velcro system to hold door back using one of the awning loops.
Awning has withstood thunderstorms etc very well. But we have had water run right under van and awning on a slope wetting the mesh carpet, soon dried out tho in French sunshine. Vango carpet got a wash after the trip and dried on the lawn, love this because it folds neatly into bag every time.
