I want to add my own car kits in one of the threads about that subject, with a few pix, but I have not found the time to do it up to now.

About this thread :
my car kits are held in two "pilot case" style bags.
One has the car related items (oil, tools, turboflares, etc..).
The second one contains a set of clothes, light hiking shoes, poncho, water, dehydrated meals + other food and drink items, Esbit stove, PSK, etc..
If I have to abandon the car, I won't need the car tools.
I will just grab the second bag. But after a few miles, it will be a PITA to walk with that pilot case. So I included a cheap, light, foldable backpack :
It will be easier to put everything useful inside the backpack and eventually drop the case.
