WE were away near Chippenham and although surrounded by hedges we still had a debate about our poled Kampa porch - in the end glad we followed the consensus of opinion and took ours down - during the night wind and rain 'whacked' the side of the van in gusts, but at least we managed to get some sleep not worrying about finding a heap of poles in the morning!
From previous experience hammering the pegs (at an angle) into a hard-standing surface might take some effort but they pull out with ease and are therefore vulnerable to getting loosened in the wind leaving elements of the awning flapping about - on that occasion I opened up the 'doors' on both sides at 2.00 am to allow the wind to blow through as the wind was from the front which perhaps saved the day as several other awnings (and ext covers for MH screens) were damaged during the night but ours lived to see another day.
