Yeah, my BOB is a truck too.

If I'm bugging out from a wildfire, I'll have loaded it up prior to the bug-out decision and I'll simply drive to a hotel out of the path. If it's an earthquake I'll make a decision based on availability of utilities. Hopefully the truck won't be part of a collapsed former dwelling.

If I need to bug out from SOCAL for some reason (widespread social unrest comes to mind), reliable transportation is a prerequisite. I'll preferably be out ahead of the masses and have fuel stops available to get to my destination, but in BOB mode my truck has food, water and shelter. All I need is (lots) more fuel. Depending on the severity of the social unrest that may be an issue.

In any case, a BOB that looks a lot like camping gear may be exactly what is needed. It all depends...
