No. You've missed the point. No Beach owner would want or need the rear window storage all of the time.
I used to have reservations about these rear window bags blocking the rear windows however now that we have a set it isn't really an issue. We only use them when on a camping trips or touring when there's only the two of us. The rest of the time they are removed and stored in true Beach fashion.
The Van Essa bags are superb, well made, easily fitted in a jiffy and provide removable storage and a bed side table all in one for both sides of the bed. We keep clothes, head torches wash bags, car keys etc in ours. You can reach it all from the comfort of your bed. If you a staying in a B & B or hotel each window bag can be removed and taken in as a suitcase. The loss of visability isn't a big issue.
