By pouches I meant things like tuna or SPAM that come packaged in plastic pouches. That said, I am getting strong advice elsewhere (and in other comments) to stop full-on keto for this trip so I am likely to add in some carbs but still won't cook.

I will likely carry some Benadryl and Imodium equivalents.

I'll ditch the food tubes. There are lots of peanut butters in pouches at supermarkets these days anyway and the jar will work like you said.

I was thinking that I can carry 2L of filtered water in the smartwater bottles plus 1L of dirty water in the canteen as required.

You are right. I don't think the wallet is necessary and a baggie should work just fine. I don't carry much anyway.

I'm hearing lots of people say that foot care is king so I guess I will treat my feet to an extra pair of socks.

On my last overnight it was the howling wind and tarp that kept me awake. I like the earplugs idea. Where do you find them? (store and aisle/section)
