I must comment on Sprokets last post.
Sadly both the sites he points to are third party sites and as such the information contained in them has been hand entered, and may include erroneous information. By all means use them as a rough guide, but before spending money do check either by measuring or asking the dealer or manufacture.
The second website linked to by Sprocket contains a diagram which displays the correct method of measurement to use when choosing an awning.
To remove any vestige of doubt I will reproduce it
Take a length of string or twine and measure from point A, inside the awning rail across point B to point C
Every caravan related forum on the internet is 'hand altered' and may, or may not contain erroneous information John.
Many of the links shown on this and other caravan forums could be described as 'third party'.
When forum posts in general are subject to almost an almost constant barrage of pedantic criticism those seeking advice rarely return to that forum when their queries are driven off topic, and those offering advice which is also frequently criticised and driven off topic as often as not decide to migrate to caravan forums where the level of scrutiny from others is rather less.
