Van Bulkhead Safety

[Haironyourchest]

Watching crash test vids on YouTube this eve, got me thinking about unrestrained cargo and bulkheads. My 04 Kangoo has a really Mickey mouse bulkhead, if you can even call it that. A few tubes with weak mesh in between, no way it's going to stop a generator, heavy tool box or 10 bags of cement travelling at 30 - 80 mph. Research reveals that even solid bulkheads will buckle under severe impact, apparently the aftermarket ones are only required to be rated for 25kg at 30kph/mph or something. There are tie down points, affixed with an 8mm bolt, but I wonder if that is actually enough to hold a heavy load? I have a couple of boxes bolted down to the tie-down threads, one is plywood and I have a notion the box would actually shatter rather than pop the bolt. Bit worried about the whole thing. I really don't want to have to ratchet tie-down every tool in the van. Thinking about fabricating a really strong metal box as big as the van bay, maybe a foot tall, with a hinged lid, and bolting that down to all four tie-down points, but that's nearly more difficult than building a metal bulkhead. Any thoughts on this?
