This is an extremely important discussion and I'll be very interested to see what information is contributed to this thread.

I won't even camp for long without showers. This would be a huge morale issue and sanitation is not to be sneezed at....

And toothpaste.

I tend to buy soaps and hygiene stuff on sale so at best I might have six months on hand. If I got into my dog's shampoo...

First thing I'd do is stop being so liberal with soap. I measure laundry soap but otherwise don't measure what I use now. And compared to a lot of societies, Americans are obsessive about bathing so we could probably bath less often. Maybe every other day, that would stretch out supplies considerably.

Great topic.
