Unless you have room for a divorce lawyer - don't even think about it! I have always liked the look of the Harrington porch awnings; however, they have a twist and turn locking on the poles, which in turn twist out of the brackets against the caravan, they also have a locking gadget. At the outer edge of the ridge pole there is a half inch prong which goes into the hole is the "across the front roof pole". Needless to say, the slightest wind the the prong comes out.
We were lucky, the bl....... thing was ripped off the 'van at Christmas whilst we were up near Pershore. It was coming home to be ditched.
Go for something else.
