Awning size and fitting

Hi everyone, hope the season has started good for you all. We have been out a couple trips up to now. Anyway, to my questions.

 We bought a new awning last year and the size was recomended by Highbridge caravans down in Burnham on Sea last year. The awning is 2011 Outdoor rev, New Hampshire (925cm)) as taken from the 2001 isa charts. Lovely awning and easy to put up with it having the new lightweight poles.

 We have had it up only once since buying it and then it semed to be a little on the short side to me. The back end was curved really nice around the caravan. The front however seemed to fall short. This ment that the Plastic type membrane seemed to have to cover the gap left where the awning beading ended, which would be more or less where the awning rail finnished.

 We just could not seem to get the corner set right at all. Looking at awnings in magazines, they never seem to show the front end fully or show them from inside when they are up. Looking at other peoples awnings when we have been out and some are like ours and some seem to have the material further down to the ground and the plastic membrane folded inside nice and tidy.

 Has anyone have the same problem or is it just us having the wrong size awning and maybe get a bigger one (1050cm). Thanks for any replies and advice.
