You can all of those things with 12 volts, just get a deep cycle battery. You could even recharge it with your truck if needed. I setup a similar system for a very remote camp once. Deep cycle battery and solar panel. We ran lights, music, and a fan at night to keep cool.
No inverter required. Just get 12 volt lights, fans, etc...
This. Get a deep cycle battery and a trolling motor battery bank like this:

You can plug in a cheap inverter and run whatever you want. I've had one for years. Bought it for a little hunting boat and ran a motor, phone, radio, lights, etc...also use it for camping and in the bed of pickup with a camper for a dog fan.
