jk had one erected yesterday at bus types and it looked quite large. i'd stay with khyam though as they look and are much stronger and you get what you pay for
UPDATE - Thanks to all your advice I purchased a Khyam and have just returned from our first camping trip and must report back to say that the awning was a winner. Tent design has come on since I was a child and it is amazing how simple the tent goes up and down. Well worth the £380. Anyway some pictures... Cheers, Kevan
