I think this is a well designed truck a lot of planning went into it and I can tell it stays super clean thanks to all the doors. I also like that all of the tools are made by one brand and they’re all battery operated.
I watched the video a second time, he didn't appear to say H20 tank size, nor the pump GPM, knowing these trucks generally, I'd say the tank is a poly(plastic) tank & holds approximately 3-400 gallons of h2O, I don't think there is an additional AFFF tank for foam concentrate. The PUC pump probably delivers up to 2000 gallons per minute( GPM). I hope that helps your understanding! 👍🇺🇸
