Awning size for Pegasus Ancona GT70 2018

Hi - after some advice- considering upgrading to a new awning for our GT70 Pegusus ancona 2018 model.  We like the look of the Vango kalri 420 ii, I a wondering if anyone has any experience of this awning generally, but specifically the sizing for the caravan we have.

I dont want the front of the awning covering the front window if it can be helped.  Ive measured up and seems I have plenty of length, but wanted to know if anyone else had this outfit?

thanks jamie
