Wow, you like to carry a lot of stuff. Back when I was backpacking, I carried a Jansport external frame backpack,

and limited myself to 40lbs MAX!
I'm a big fan of MREs, and have a couple dozens here right now.

I used to carry Mountain House freeze-dried meals, but they're just too darned expensive. If you want dried meals, just go to the grocery store and get some packages of Knorr/Lipton side dishes. They're excellent.
Of course, you're going to need a stove to cook these things on, unless you're planning on perfect weather to make a campfire. I've been stuck in a tent for a couple of days, and would have been really unhappy without one. This one is close to the 30yr old one I still have, and it still works:

Don't sleep under a tarp. Get yourself a tent.

Trust me, depending on where and when you're there, the insects can eat you alive.
For drinking water, get yourself some Potable Aqua tablets,

They're not particulary good tasting, but you won't get sick, either.
Well, that's my 2 cents worth.
