We've worked it out like this:

In one minute, I can have the family out the door and loaded into the rig with their clothes changed and their BOBs with them.

In two minutes, I can include two grub boxes and a handful of firearms and ammunition.

In 5 minutes, I can include a chest freezer, a wall tent, 4 sleeping bags, a box of tools, my chainsaw, and additional food and clothing.

In ten minutes, I can be fully loaded, 5 miles down the road in any direction, and determining which destination is the most suitable for the situation (next nearest town, heading for the mountains on back roads, headed for open country away from the things of man, or at the airport to hop a private flight).
