We contacted the retailer of our snow boy awning and was told by the sales manager the reason the eyelets had elongated was we had not used the optional extra
Val explained to him that we had not been informed they existed and if they were necessary should be issued with the awning,and they clearly state on the isabella web site these attachment are optional extra;s and that guy rope attachments for a 4 season awning should be strong enough to withstands winds much stronger that the 22MPH gusting to 36mph, also we asked him wat he sugested for the top eyelets as these were the ones that bore the most pressure He did not know But said that if it was him useing the awning he would not use guys with such a strong frame 
This is the email I sent him
Re your conversation with Val Rudham on the 12 October 2011 regarding the extending guy rope attachment eyelets elongating while in use.
Please find enclosed photo's of the Eyelets
IMG_0370 is one of the bottom 3 eyelets
IMG_0369 is the inside view of one of the top Eyelets
IMG_0368 is the outside view of IMG_0369
IMG_0353 in a view of the awning set up and guyed down.
When the guys are fixed the elongation is around 50% more but when under pressure from a Wind 22MPH gusting to 36 mph
the eyelet is elongated to double it normal size.
and I know that a guy rope connection should be strong enough to connect a guy rope to, and withstand all the weather and winds from a 4 season awning.
Since receiving this awning I have been informed of an (OPTIONAL EXTRA) for winter Guying but only showed on the bottom three eyelets
as these three eyelets are not heavy load bearing I believe they may be a time saving optional extra. but in my opinion totaly unsutable
for the top three eyelets that are load bearing and require to to very strong on a 4 season awning.
Our concern is that the next time we have strong winds one or more of these top eyelets are going to let us down.
Would you please reply to this email with your suggestions about safely guying this awning down throughout this coming winter as we do not want to be let down after contacting you for assurance that this awning is up to the require standard to use all seasons.
The comment you made about not using guy ropes and just relying on frame strength is very bad advice to give to a camper, as know one really knows what the wind will do while you are sleeping. All securing lines and pegs should always be fitted whenever an awning or tent is pitched. as the guys stop the frame from been pushed around by the wind eventully weakening the frame this is a well know fact within the world of frame tents and awning.
I understand you will discuss this worrying problem with Isabella Awnings and we look forward to receiving a solution.
Best regards

I will keep you informed without naming the company concerned.
Good e-mail that is; Wonder how they respond?
