Good questions. Right, stuff sacks. Depends on your system and where you have your tent (inside or outside your pack) and whether or not you use a pack cover. Personally, I use a pack cover over my pack and my tent is lashed vertically to the back of it (a Vapor Trail), this seems to work. I tried putting the tent in a garbage bag (when i didn’t use a pack cover) but it “sweated” and became damp anyway.
I always put my sleeping bag inside a garbage bag, it’s saved my hide a few times. I also line my pack (before filling it of course) with a sturdy garbage bag, you know, the thicker types. Until now this method has never failed me and everything inside has stayed dry, including those much appreciated dry clothes at the end of a day in the rain.
I’ve carried peanut butter before, mainly for lunch with bagels or something. I can usually polish off one of those squeezy tubes in a few days, they are better for us hickers than the glass jar types.
I’m with you on the tuna/salmon thing. I always carry those foil pouches, whether it be for lunch or to add to my dinner. I also like the fact that you can buy foil packed tuna in a variety of flavors (hickory smoked, zesty lemon and sweet n’spicy). A great substantial addition to an otherwise low nutrient freeze dried meal.
Wish I could help you with the t-shirt deal, I’m sure someone will respond who knows all about it, and more than me about the rest of the stuff.
Good luck!!!
