and when do you know its knackered?
We've had our Outwell tent for 9 years this summer. Its still going well apart from where DH used the stove and melted a hold in the living room groundsheet. There's also a tiny hole in the bedroom groundsheet where I think a stone must have been underneath. But some duck tape seems to have fixed those OK.
We use it for at least one week a year, plus some weekends and sometimes a 2nd week as well.
Is it likely to keep going for much longer. I've sprayed it with re-waterproofing stuff once but never had a problem.
When its past it will it start leaking or are the holes likely to get bigger?
