A well equipped overland expedition will turn your Land Rover into a home from hone, with most likely a built in gas cooker, sink, fridge, water tank and all manner of cupboards for securely storing cutlery, crockery, food and drink.
But even on a greenlaning trip its nice to be able to stop in a pleasant spot with a great view and brew up a cuppa on a gas stove.
You could carry a kelly kettle, where by burning twigs and scraps of paper in the central "chimney" you can boil up water in the outer cylinder in no time.
Whether you are crossing a continent or the Cotswolds, my advice is the same, bring along what you need, but stow it away carefully so its not rattling around in the Landy. Everything should be packed away and secured properly.
When heading out for surf trips abroad, I usually carry the simple things that are cheap and easy to prepare quickly. I carry a small gas stove with replaceable cartridges, and stock up on things like pot noodles, pasta and soup. I have tended to buy fresh bread everyday, and always have loads of bottled water on board.
Bottled water is readily available in most countries, but if you are a bit further afield then check the seals are intact and haven't been tampered with. You can also buy sterilising kits that allow you to treat water to make it safe to drink.
Living out of a Land Rover is fun, and something I love doing, and if you haven' tried it yet, I urge you to give is a go.
