we're off to cornwall but with the expanding amount of things we need to take with us to set up camp we need a roof box for our car.

now i have absolutely no idea where to start with this apart from the fact that we don't have slinky rails on the car so need a roof rack contraption and that thule seem to be most popular when scanning other peoples cars!!

any recommendations? or indeed things to avoid?

Anyone had a thule foldaway box? any good or too flappy in the wind?

thanks
