Doubling up on equipment Car kit / Bug out kit

[ukphil]

Hi

What is your thinking on doubling up on supplies & equipment across the different car and bug out kits.

I have completed my 72hr emergency car kit, which is well equipped. It could sustain me for 72hrs of the family of 24hrs.

I,m now looking @ sorting out 72hr bug out kits for each family member to be kept in the home

For me, it does not feel right doubling the supplies & equipment I already have in the car kit.

I would generally expect the car to be wherever I am and if we are bugging out it's most likely by car.

So to complete my home 72hr bug out kit, It feels that I should simply just top up the car kit and keep the top up in the house, nice and handy to throw in the car.

Or would you suggest a completely separate kits ??

Also I'm putting kits together for other family members. Should we each have identical kits [supplies & equipment] or plan to share. ie cooking, whislte etc. ??

Thanks

Phil
