Someone early in thread had sidearms in three or four calibers. If you feel you have to have a weapon(s), it is probably best to have one caliber for all e.g. .357 pistol and rifle. Otherwise, you may be like Captain Bluntschli in Shaw's "Arms and the Man" where his unit winds up with the wrong ammunition at the start of a battle and have to run away (I mean retreat)
Don't have a chainsaw (wish I did) for the same reason given on previous page by PRodacy. Trees can fall down. We have a collapsible bow saw and that has proven useful the one time we had to use it for a 10" or 12" log going in to a nice dispersed site. We were scouting area in our pickup. Also have a nice Swedish axe that will probably lead to physical collapse if I ever had to cut through a large downfall. At 75, moderation is no longer an option.
I read through most posts on this thread and a compressor must have been noted but I did not see this. Consider this an absolute necessity. Our 1 kW generator will not operate it (should have gotten the 2 kW) but we have sufficient battery power to run the compressor. We trialed the PSWI and battery suite at almost 4 kW once (AC, hot wter heater and microwave simultaneously. Not something to do while camping.
