Coleman stove. Mine lives in the back of my elderly Range Rover along with the recovery gear, a kettle, some dixies, and some basic staples (tea, coffee, aeropress, instant noodles). I've always got a few litres of drinking water, and in any case I live in Scotland where you're generally not terribly far from perfectly drinkable water that's just sitting right there on the ground often spilling majestically over rocks and waterfalls which are slippy as hell when you go to fill the dixies and which you will get to experience right up close, considerably closer than you intended.

There is nothing like sitting on the tailgate up at a remote hilltop site on a pleasant spring day, drinking a cup of tea outside in the sunshine while you wait for the third attempt at a firmware recovery on a radio repeater to finish, contemplating chucking some sausages on for lunch.

Except, possibly, sitting inside the transmitter shed has it gets buffeted by storm winds listening to the rain battering against the roof and drinking a nice hot cup of cocoa as you wait for the 17th attempt at a firmware recovery to finish.

And if you run out of the expensive special magic Coleman fuel, it runs just as well on mogas so you can pop the inlet hose off the injector rail, scoosh some into the stove tank, and get right on back to cooking your dinner.

Me? No, I'm going to be out on site all day long, I won't be in your Teams call. Tell you what, want to come with? It'll be good for you to see some of the hardware in use. Grab a steak or something to do for lunch.
