Many BOB/GHBs youtube videos do have some useful information as to the kit, but I suspect that there is a good proportion of the tactical survivalist prepper guns'n'knives'n'ammo folks on Youtube have never actually spent a night out under the stars. Many of them use Alice Packs for their BOB but thats not a problem though as the beer belly counterbalances them for pack weight distribution..

The number of folks that don't even pack a sleeping bag or warm clothing let alone a sleeping pad is quite astounding. It does get cold even in the desert at night time!
