We beach camp Fraser Isl a lot and the winds are usualy a consistant NE or SE, so we set up as best we can with the camper end walls facing the winds, being backed by high dunes also helps, still makes for wild sleepless nights in 40+ knt storm winds though ..
One thing that was the biggest movement makers for us was the hip shaped awning acting like a wing ..Would have been a lot better if it was a flat type awning.
Regardless of weather [ Short of a cyclone of course ] we go camping, just takes a bit longer to set up sometimes is all .
