Also a free standing self priming pump and end filter for a hose, so you can pump water, if need be, from a stream or pond or cattle trough.
I wouldn't recommend that in almost any country unless you are prepared to go to great lengths to sanitise it. No need anyway. You will always need fuel every few days and most (but not all) fuel stations have potable water supplies and we have never been refused a water topup when buying fuel..
We use campgrounds or fuel stations often enough to be able to top up with water from their faucet and I mostly added some ordinary unscented laundry bleach to make sure. Never had a health problem from water out of water systems and occasional mountain springs across more than 25 countries including a few that would likely be regarded as third world. As always those with compromised immune systems might be smart to use bottled water.
On food eat only where the nicer clothed eat and be selective. Fruits and vegetables are safer than meats. Any meats cook until you know it is done. Might mean a lot BBQ. Drink wine with your food. This is what keeps so many in Europe from throwing their guts up. The alcohol does kill bugs but not all of them.
Where do you get this stuff from?
