Thanks for the fix idea Drover worked a treat. Think I might leave it like that to as I spoke to a canvas place the other day and they said yes it would be expensive to fix but as she said all you are going to do is put the same stuff back in. Maybe Jayco need to look at using a vinyl mesh or something that is a little bit stronger than what they use now.A quick fix is put some sticky tape over the tear on one side then put a bit of aquadere on the other side, remove tape after it all dries. Not all that invisible but it is flexible and helps keep the bugs out.
