Last thing bought was a new sleeping bag and a fridge. My last trip was in colder weather than normal and I got colder than I like when sleeping, so I finally decided to do something about it. The fridge is something that I've been wanting to do for quite a while, and the time hit where it was right to do. I haven't unboxed the sleeping bag yet, but that fridge immediately got set in front of the wood stove (best access to an outlet), plugged in, and run through its paces. Got to fridge temps pretty quick, and I was really surprised at how fast it started freezing the cup of water that I put in it as a test.
Next "purchase" (more like project) is to estimate how much power the fridge uses and buy the parts for a solar generator that can keep it going under common PNW conditions. I've got one that I built a while back that is smaller, and I learned quite a bit from it. The new one will have an upgraded charge controller (MPPT instead of PWM) and bigger battery capacity (I'm thinking a smaller battery size, but 3-4 of them, to balance out in a "bank").
