I've had plants die off because of abrasion, too. A good technique for short moves, up to three days or so, is to wrap them in wet paper towel, put them in a plastic bag, and put them in a box. It keeps them from being broken apart by water sloshing and, for delicate plants like Cabomba caroliniana, is a good approach. Other plants, like Ceratophyllum demersum, do not suffer from abrasion all that much. It depends on the species.
