We have a 4-6 man airbeam tent (Airgo) and are contemplating the extension to it. That said, loads of the review are pretty negative so instead of an extension, we are contemplating an event shelter that DH can cook under and we can sit on our table to eat under should the weather be bad/too hot and therefore needing shade. We are camping for 4 weeks in the summer around Northern Spain and France and we won't bother with the faff for short stops but for the longer stays, we'd put it up. We could even have zip in mosquito side nets so that we keep the bugs out.
Does anyone do this?
