Could be a last 5 second steal on an ex display RV4 here. Norwich camping are good. I have had loads of gear from them Sitting at £450 at the second. They're £695 new. Anything around the £500 mark would be a bargain. If that is you think a tent is worth anything like that in the first place. They are very good though and will stand the worst UK weather as I have found out
