Hey! I'm loving this mod, a suggestion though, maybe you fellas at Project Nostalgia can add a tank wagon? I would think it would be quite efficient, especially with the 3 forest areas around the map.
Off the top of my head here is information about them if you are not familiar:
Tank wagons (officially called as "tank wagons") were the tankers of the Los Angeles Fire Department, dating back to the 1930s, and in service to this day (LAFD currently has 2 tankers per Wikipedia). Tank Wagons of the 50s-80s generally had 350-2500 gallons on them depending on the make/model
This one, Tanker 97 has 600 gallons on it, really for brush fires with smaller hoses, it also has a bunch of supply line, and I believe two handline hookups, used by the mountain patrol.

This on the other hand has 2500 gallons of water on it, with a little more supply line but the same amount of handlines able to get pulled off of it, 2-3 connectors, way higher capacity pump and tank, this was used by a station that was closer to the brush, but not a fully fledged mountain patrol truck.
