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.
