Tips for Managing Power Usage While Boondocking?

Simply put, plan what you think you will need for the duration of your trip. In my case, a couple of 235 wh 6 volt Golf cart batteries, along with hot water and cooking on propane, get us thru a 3 day weekend, in spring or fall. Anything longer especially in July or August is when I bring our genny. That works for us..😉

Safe travels and all the best.

It all depends on the type of camping you do. We normally make it thru a long weekend on our batteries. If we camp during July and August we bring our genny to be able to run our AC etc. Otherwise we run on propane and batteries. It doesn't take the genny long to charge the batteries. with solar you still have to deal with cloudy days and your batteries won't be enough to run the Air conditioner. As far as I'm concerned, bring your genny. It's more reliable than the sunlight. 

Just my $.02 FWIW

Safe travels and all the best.

Haven’t carried my generator since I installed solar in 2017. Bigger exists but we do fine with a 200 amp Lithium battery and 300 solar watts. Well enough not to worry about power. 

Just get a generator, properly sized, then you can use the microwave, air conditioner, whenever you want, no problem.

Add another battery is the easiest. Generator next. Solar seems like a lot of work.

If you go with LiFePO4 batteries, then also consider getting a converter that can charge them (unless yours already is able to). Even with running generator a few hours per day, a good converter can replenish those batteries to 80% pretty quick (compared to lead acid) in my experience.

But yeah first, you used the word “battery” in singular tense. Unless it’s an 8D (if you know what that is) or a billy badass big Lifepo4 you can manage all you want but short of reliable charging or switching to candles and a camp stove it ain’t gonna go very far.  
seems counterintuitive to manage electricity to the nth degree. At that point it’s a box with a terlet and a nice bed. May as well get a cargo trailer a cot and a bucket. 
Air conditioning or winter weather heat aside, 2 golf cart batteries and a charge every day w a genny is a good. I I’m in starting point. 
add solar, add storage (more batteries), learn how to actually manage it (like how much juice it takes to run an inverter for the same result as DC powered stuff.  
PS, a luxurious boondocker setup that you can actually enjoy all the rv functions in whenever you want is cool. It just takes $.

realy its a bit of both having a way to charge your batteries, having enough battery capacity and power managment.  

what do you have for battery/ies right now?  if its just the one the dealer throws in then you are going to have issues.  so what you have to figure out is how long your battery last with what you are doing right now and how long you want it to last.  for example if your battery starts going dead after 1 night and you normal go out for a long weekend type things then you need over three times the battery capacity.  the good thing is that the batteries that come with the camper are only 80AH and if you want them to last you can only use 1/2 of that.  but for a rough referance if you are using up that battery to the point where you lights start to dim in 24 hours then you know you are using close to 80AH in one day.  

so the easiest thing to do right now is put better batteries in, so what I recomend now is people upgrade with LiFePO4 batteries.  for usable AH they are the cheepest battery you can get per AH wise and also by life span.  so for instance you could go out and get something like a wattcycle 314AH mini.  so thats almost 4 times the total capacity but the difference is with LiFePO4 you can use 100% of the capacity without worring about shortining the life of the battery as they are traditionaly rated at 100% depth of discharge, plus there is no maintenance aside from fully charging them once and a while to keep the cells balanced, and the life span is much much longer than a traditional battey so you will probably go a ong time with out having to replace batteries unless you do something to it.  

with the right capacity you can camp as long as you normaly want to camp, then later you can add solar which if sized right will let you go indefinatly, or at least till the tanks need dumping 😉
