Have just returned from camping on Exmoor and our SIG was letting in water through its seams, I did find a couple of small holes which I repaired but then realised it was coming in all along the seam in our main living area and dd's bedroom (which has no holes and hardly any wear. We've only had it since last summer, and spent about 15 days camping in it (spread over 5 trips). We've had a footprint groundsheet for most of that time. Vango are saying return it to them and they'll quote repair costs - which from looking at their website will be £50-75 for a new groundsheet. I don't want to pay this if its gong to start leaking again! Would rather buy a different tent. Unless its just faulty and should be covered by guarantee. I've sent another e-mail off to Vango asking this again. Anyway has anyone else experienced this? Should I have been waterproofing the groundsheet seams? I do the main tent. What do you all think!
