I am a great advocate of Folding caravans. 5mins to set up and get the kettle on, no worries about wet pack downs and 4 solid walls around you. Mind you there are just 2 of us and we use a 4 berth ( keep one area set up as bed ) so if you have children you will still need an awning for extra space.
Mind you with the awnings you can get these days you can still be set up withing half hour ( using carbon fibre frame poles )
There arent as many around as FC's and TT's an we bought an older one and are doing it up, buit if you have a decent budget you can get some excellent ones for a good price. Worth a look at least if you haven't thought about them before.
