I wonder where we would be if our ancestors were as risk averse as the majority of our forum members?
Well, most of them probably weren't cruising down the highway at 75mph with many of the other driver's buried in their screens. Some that took the risks of their day came through fine. Others died young. Some that mitigated risk lived longer; others died of something else anyway.
For me it depends somewhat on the difficulty of mitigating the risk vs. my enjoyment. For example, wearing a seatbelt takes nothing away from my enjoyment. Even though my ancestors (and me as a youngster) didn't wear one, I wouldn't have any reason to leave it unbuckled now.
On a bulkhead: For me, if it ruined my van plan I would probably not have one. OTOH, if it works with my plan, then it is not only safer but provides great temperature control from the cab. And maybe it's more enjoyable because I can have my magnetic knife rack, books on shelves, or whatever floats my boat and less chance it will fly into the back of my head.
If I didn't want a bulkhead, and hadn't built my van yet, why not build the cabinets in a safer way if there is one? Avoid the obvious "flying matchsticks of cabinets" way?
Your reply seems to imply that anyone who takes safety into account is a modern-day weenie. But when I see pictures of the tough ol' cowboys in pioneer days, I still see them circling their rigs by the fire for security at night.
