Definitely make sure you keep the roof emergency tie-down kit in your van on and not on the shelf in the garage.
We had roof failure in one of the most remote spots in the Scottish North West Highlands, that is, with the roof stuck up. Ended up having to drain the hydraulic fluid out of the system ourselves.Then using the tie-down kit, drove all the way across Scotland to Inverness to get it repaired. A journey that would have been nigh on Impossible if we had left the kit in the garage
