In reply to Claire Carpenter:
I don't have experience of Spain specifically, but loads of other places. My initial view is that unless you have an ex-securicor van then beefing it up is entirely the wrong way to go.
When I was with the Germans in Finale years ago they would do everything they could to make their vehicles as undesirable as possible and as empty as possible. They removed the seat bases from the seats they weren't using, the fairings off the motorbikes etc. Whenever they parked up they would leave all the windows open, the doors unlocked and nothing in the car of value. The one day Uri did lock his door it was screwdrivered open.
When I park in 'bleau these days I open all the cupboards and glove box, remove the rear parcel shelf ( part of the bed) and ensure there is nothing that looks like it is trying to be hidden.
(I don't leave it unlocked as that would probably invalidate the insurance.)
How well can you fortify your van?
Are you just changing it from 30second withstand to 2 minute withstand?
If the crag is 20 minutes walk away, is that actually of benefit...
( TBHmy experience is very out of date, so just offering it as a point of view, not claiming it is current)
