Hi Ruut,
On our recent six week trip around France we did not use the tonneau a lot and for the long drives we pretty much always had the sidescreens on. The "new" hood is so quick and easy to put up and down that we used that rather than the tonneau. We store the tonneau in the sidescreen bag in the luggage rack so we don't have storage issues. When we did have the sidescreens off then the tonneau would be on all the time, tucked down over luggage behind the seats whilst driving, so again we had no storage issues.
I also often drive alone when the tonneau really comes into its own covering the passenger space and reducing drafts.
Best wishes,
