Yeah, I get you on that, but I never spend the night very far from the vehicle I use for getting to the area where I am doing something, I am unlikely to leave the vehicle unattended, and when I start factoring storage space, weight, cargo volume, time and fuel constraints, MREs keep coming up the winner. Then one last stop at the dollar store before heading out to grab gallon jugs of water and some energy drinks.
Mountain House a close second condisering that my off grid stuff has microwaves. The motorhome has a conventional microwave and the new setup that I am putting together as the eventual replacement for the travel trailer is getting the 12v microwave I bought a few years ago. That goes with the Mountain House stuff, in fact, the microwaves get stuffed with mountain house pouches for transport anyway. When making some food, I pull all the stuff out of the microwave, then put back what's left after cooking. Another issue being trash disposal. MREs and mountain house mean no dirty dishes. My version of "no trace camping" involves garbage bags and worst case scenario, campfire and a shovel.
In all of the scenarios I look at which involve bugging out or storing pre-positioned supplies. Cargo weight and storage volume are cost issues, so I factor out water storage and minimize wet food in general. What you would see around my stuff is large empty water containers, pumps, hose, filters, not a lot of water except some commercially packed galling jugs and maybe a couple racks of water bottles. Hate to say it, but the rack of water bottles are also a grab and go sort of thing at any refugee camp type places. Seems to be the first thing they ever get to handing out in quantity.
Besides that, my main SHTF plans involve mostly bugging in, assessing the situation and then putting together a team to go raiding the fuckers who ripped off my supplies and screwed my people over. Raiding parties need to travel far, fast and light. That just don't happen like a long three day hike in the mountains.
