Hacks? Hmm, not so much hacks as just conserve. Make everything you own do quadruple duty.
Like coffee filters. I hate coffee but hubby loves it. Google what to do with coffee grounds and you get like 20 options to use those as replacements for other things. Repels fleas from your pet. Put in bowl outside to repel skeeters. Put in small bowl inside for odor control, wonderful for hand scrubbing to remove smells and dirt. Coffee filter can double as a laundry dryer sheet, add bit of vinegar and touch of smell you like and tumble and you don't need a dryer....place slightly damp clothes off clothes line into plastic bag, flip it all around and up and down and hang for a while in the sun in the bag, take out and hang clothes again in sun for freshness factor to dry thru if you so desire….coffee filter can double as a tissue, light washcloth situation or TP if required, great for dusting computer screens etc., use as a bowl for a hand held item like popcorn or nuts.
So for us it is whatever you got, use it a gazillion ways. Everything has so many uses and all of us know these little tips and tricks to use everything we got over and over as we need to suit our lifestyle.
key things is food storage and water storage. food and water are needed for survival point blank LOL so if you conserve water tightly, military fast showers and wipe downs etc....have enough food to last a month then you got it for not having to resupply those 2 items and can last at least a month.
Collapsible water bags. Instead of full sized containers that take up space all the time, the collapsible water bags store so easy when not in use and go 'small' but fill big when out and about and you find a water source. Fill them up, come back and even store all your filled bags maybe under your vehicle til needed. A few on the roof for hot water maybe in full sun? Once used, collapse the bag til you can fill it again. You can have 25 bags to use and have space for them but not when they are full sized solid water jugs maybe. All also depending on your size of vehicle, storage room etc.
another smart key is know your area you are in....where is the closest and safest place to do what you might need...a dumpster to use for your garbage nearby, possible water refill sources and more. We can all narrow down our lives easily. But at some point one has to 'find' water and food supplies and just be smart doing just that.
That is kinda how I approach that question of not breaking camp and it boils down to when your water supply and food run out mostly
