I have sides and a front for mine that's why I went for the zip model it's a lot more quicker and easier to put up and down because as the name suggests they just zip on and off . I was lucky I managed to find a set of sides and a front that were like new on gumtree for £300 . I know some ppl think these awnings are over priced but when you use one regular you realise they are very good value for money .
As for the price think there was sale on when i got mine cause am sure the rrp is £560 so Round £400 still a great price but that's just the regular f45s if u are serious aBout adding sides and front later I would pay the extra and get a zip one
Only a extra £60 pounds and as I said make life a lot easier that messing around with all those clip on bracket for the normal f45s

As I didn't want to spend my rare holiday times messing about with a awning .
