Bedroll. Saddle blanket. Percolator, Coffee, Beans, Salt Pork, Matches, Sugar, a person can get pretty basic with camping.

""Charge efficiency factor". It is a percentage value expressed as to how much "vigorish" a battery requires to be "overcharged" in ampere hours, in order to barely meet 100% state of charge. The number can vary anywhere from around 88% to around 92%. This means if you charge a actual number of amp hours back into the battery as taken out, the percentage will indicate the true state of charge of the battery.
Charge the batteries utterly and totally 100% according to the hydrometer. Discharge the batteries 50% of amp hour capacity according to your AMP HOUR METER. It danged well better agree with a second hydrometer dip.
"I don't need insurance to drive. The car works perfect. I arrive in a good state of health".
Individual decisions are just that. When you inform someone of available methods of battery management and they choose a minimalist approach, they should not utter a word of complaint if and when a battery or batteries fail prematurely or lose capacity prematurely. But "minimalist battery amp hour meters" are so inexpensive these days, the "Can't afford one" argument is not valid. Look on eBay.
This stuff is meant to make camping easier not harder. Properly done, you don't need Mother Fletcher's Do It Yourself Battery Laboratory just to go camping. But then when "Why isn't this danged battery working? The meter was in the green yesterday" pops up, there is an answer. If you scoff at meter management with hydrometer calibrations, then subsequent problems should be suffered in silence.
When I risk something then lose the "bet" the responsibility sits on my shoulders.
