Is there such a thing? We have a T25 but actually sleep in our 6 man Outwell at the moment while the DCs are small as the space is handy when it rains. Great tent apart from being too hot when the sun comes out. We've only camped in the UK since DCs so not too much of an issue so far.
Would like to get a drive away tent so me and DH can get to sleep in the van bed. Would like cotton as we hope to get a bit further south than Cornwall sometime and don't want to pass out from the heat.
