Great kit.  One suggestion, since its a vehicle kit I would throw in at least another liter of water.  Good tobacco always makes me a little thirsty.  Also it appears your batteries may literally outweigh your water...now, cigars I can understand, but batteries over water? 

  I guess that is just the californian in me.  We are so dry out here.  With all the fires locally I don't even have to buy my smokes I just go outside and breathe in deeply.
Cheers,
Logan.
