Off grid camp setup

Hi all. I’m in a situation where I’m going be setting up a camp off the grid that we will use frequently throughout the year. A couple things about the place, we have windmill water but no electricity. This water will be good enough if I want to treat it to use for showers/toilet, etc. I will be using an inverter generator since it gets a tad bit warm in Texas during the summer/fall and we will need to be able to run the AC all day at times. Town if close by so if I need to haul 50 gallons or so of fresh water for the trailer that is doable. I’ll plan to haul black water to town in a tote and dump black water there so I’m not planning to build a septic at this point.

Now, I’m looking at how to handle the water. The windmill water is not where I’ll be camping and I’ll have to haul it, not a problem using a transfer pump and tanks. I’m going to setup probably a 200-300 gallon water tank in camp that will be elevated so that I can use a gravity fed if necessary but I am also looking at an on demand water pump because I will need water outside for tasks. Has anyone done a setup like this for the on demand pump? I planned to run a splitter off of the pump to run a hose with a sprayer and an outdoor sink. And other advice tips on what I’m trying to do here?

I’ve used generators before but not really a 24/7 setup. Doing research now on what type I’d like to buy but I’m open for suggestions here as well.

Thanks in advance.
