There are obvious alternatives to much of the equipment covered so far.
Stoves; I have changed from the old 2 burner Coleman propane stove to a single burner Gas one. (There are may others on the market) Since I no longer cook for more than myself.
I did find this past year, a small, temporary, heater attachment for the stove tha helps take the edge off the cold tent just before entering the sleeping bag (it then gets turned off).
I have basically given up on trying to heat a tent, due to moisture/condensation, air quality and fuel quantity issues. A good sleeping bag renders a heater, mostly, redundant.
I have found wood heat to be excessivly dirty/sooty; especially when transporting the components home.
12 volt refrigerator vs cooler:
It doesn't take many trips to town for ice replenishment to provide an incentive to look for alternatives.
An ice maker was considered early in the search and could be viable IF a generator is in use (generators require a lot of fuel; so this is a trade of a weekly trip to town for (cheap) ice for a trip to to to replenish expensive fuel supplies, IMO. Running the numbers, several years ago indicated that a relatively large solar electric system is needed to power the ice machine with sunlight. Note; this was quite some time ago and newer technology may have moved the break even point.
A compressor type refrigerator freezer can be run from solar panels and a battery (the base numbers, usually given are a 100 watt panel and a 100 amp hour battery.)... Technology is constantly changing and these numbers may have improved.
I have done this and it works. However, it does require that the camp be sited with access to direct sunlight over most of the day. (As mentioned before; I prefer cool, shady campsites). Like the large tent I save the refrigerator/freezer fo longer than normal trips (1 1/2 weeks or more; the additional transport and set up hassles are simply not worth it to me for week end trips).
I tried solid state (Peltier) coolers and they are, for me, a waste of time. They do not cool well enough to keep ice cream frozen on a hot day.
For port-a-poties; get one with a very large holding tank (cassette) at least 5+ gallons, and, consider getting a second spare/reserve holding tank.
Alternatives include bucket or bag based portable toilets.
for a while I was using a post hole digger a cheap tent with a hole in the floor and either a chair with a hole in it or a padded 5 gallon bucket with the bottom cut out... (honestly, I prefer the port-a-potty).
Lanterns are a thing of personal preference.
As are flashlights/headlamps.
I do still use a tap light on the end table next to the cot; it has the advantage of being easy to find and light in the dark when big foot is making noises out side at O-Dark-thirty in the morning... just tap it to light.
There is also usually a clock and a thermometer on the end table also.
In terms of security (intruder alarm) and companionship a dog is can be hard to beat. (You will, however, see almost no wild life).
IMO Firearms require professional training and while I usually have one available; near "civilization", I can whole heartedly, recommend bear spray with dye to discourage both 2 and 4 legged varmints.
If there are 2 or more people games can help pass slow periods; Chess, checkers and backgammon are favorites.
Some folks are known to camp to hunt and/or fish.
Day hiking hand wood gathering are usually part of my trips.
Running out of things to say, today...
Enjoy!
