Brush fire

I’ll start this with a story that happened today. As I was traveling to my weekend property that is only about 25 minutes from my home, a truck in front of me had some of his load fall off and catch fire. I of course pulled over and grabbed my truck fire extinguisher. I was unable to put the fire out and the side of the road shortly after caught fire and had the fire department been any slower getting there ( giving I have a volunteer fire department and they did good for the ability’s they had and the fact that no one was at the station at time of the call) the wood line would have caught fire and could have effected my bug out/ weekend property the was only a few miles away. My question to everyone.... has anyone had a issue like this and know any ideas of a reusable bigger fire suppression system?
Thanks in advance for the help !!!

About two years ago a wildland forest fires was threatening my home and my cabin (bugout location) 70 miles away and threatening access to my backup to the cabin all at the sometime, it's not a comfortable position to be in. It's after all the planning the feeling of being hit in the gut sets in.

On my property, I have a generator backup to my wells, I use a center-pivot to keep my grounds saturated, I use 4x8 corrugated metal sheets I can move around and put in the most threatening areas, all my roofs here are metal, I have two portable tanks with a high volume gas pumps that feed a 3" flat-hose. We also have pumps we can place in the creek (creek is 4' deep 7' wide with high CFM) In the vehicles one is limited unless one wants to drive around in type-6 truck with 150gal tank.

We don't have the fires like you guys do up north, but one thing I do know is to keep trees away from the house. That way if they do catch fire, they at least won't fall in your house. I'll take the hurricanes that we have down here verses a forest fire any day.
