Can you access the water in the tank, without the aid of the onboard pump? Wouldn't do much good if there is not a manual way to extract water. Even if it had a drain on the tank, 625 gallons kind of exerts alot of pressure, and I doubt you could put the plug back! <img src="/images/graemlins/smile.gif" alt="" />

As for "food", I have seen "high energy" bars, that are like 5000 calories or something. Those might be a good back up. Having real food would be better. If I remember correctly, I think you need more carbs, than protein, in a "survival" environment. So, since you have water, rice, or pasta's may not be a bad choice. Light and easy to store. For protein, you might try dried beans. (Thanks Alton Brown of Good Eats! on Food Network)

I don't know if expending the energy to hunt, kill, skin and cook animals would be worth it, assuming you have a 7 day food ration kit. Bringing something along to protect yourself from any animal that seeks the same high land your on might be good. These animals I would think would be hungry too, and you've got food!

I have a couple of questions:

- When you are "cut off", are you:
- At the station?
- On high ground?
- In survival mode, with not expectations of performing firefighting? (No? Toss the hoses off the truck and use that area for storage!)
- What is the weather like?
- Can you not store more supplies in the cab of the engine?
