Looking for something to stash bags of clothes and other bulky but lightweight and non-precious stuff on the car roof when travelling with family. (Big sheet of polythene and tie-downs works but always seems to involve me struggling in wind and freezing rain putting it on!)
There seem to be decent-size (>400l) boxes at around 100 notes, or bags from about half that. I suspect that the bags are never going to withstand driving rain, and wonder how long the zips last, but not sure whether the boxes will just fall apart either.
What experience do folks here have of such things?
