You should look into getting a pressurized water (PW) can. It holds a couple gallons of water, and you use a tire pump to pressurize it to the correct psi. You can put out a lot of fire with one of those. You cannot use it for kitchen or grease fires, you would need your blanket and abc extinguisher. But for putting out burning wood, or hay, you need water. It sounds like you are very remote and don’t always have a water source nearby, so a PW can could be very useful for you. We use them for class a fires, like trash, debris, or even hard to reach areas like an incipient fire in an attic. Also a little dawn dish soap mixed inside the water will help coat things by reducing the surface tension of the water.
