The Box carried tents, sleepy bags etc and at times enough gear for extended, up to 6 weeks, trips. Not always in UK.
On US79 heading for Lake Erie, real nice day so our leathers were stashed in bin bags on top the box
Not all days were uneventful, this in some forgettable Belgian town en route to Jabbeke.
Again bagged leathers on the Box.
The dayglo bundle on the rack was camping gear being carried friends.
But they are past glories!
Today that box carries very little other than being a helmet, jacket, boots etc store.
