Hi Everyone, im confused. I have a 2015 bailey unicorn cordobra and am thinking about buying a full awning for the long summer holidays. The extra space would make all the difference to the kids ect. 

 What i cant get my head around is the size i need. Im looking at a second hand isabella or ventura. Bailey say my "a" dimention is 1091cm Isabella say its 1087 and size 1100. But  then they say their size 20 which is 1050-1075 is ok. 

 How critical is it? Do i have to look for a 1100cm awning or will a 1075 be OK?  Why do they the size some as 1050 to 1075. 

Some forums ive read say got a bit smaller as tight is better? 

I have only ever had a porch so I am really confused and if I buy 2nd hand I need to know whats size i can get away with

many thanks rog
