Amazing that it’s been recovered 🙂
I keep meaning to make a few changes to my van, although things like large plastic roof lights and no bulkhead mean any security upgrades are always going to be limited.
Security window film on the side windows of the cab as it takes a little longer to clear the shattered window (often enough of a deterrent to put off a chancer)
Old fashioned steering wheel lock (although my van is Iveco and apparently the immobilizer on them is practically undefeatable (they have a non-standard OBD too)
Handle/lock armouring I’m not sure about…it would need to be a naive thief to bother trying to prise the locks out when there are windows in the side, although the camper ones are double glazed acrylic so probably harder to break than the glass ones.
