Camping Gaz (blue mark) Cuisine?
I'm camping gas stove. The only problem is that the cartridges will not last for long teacups and kitchen. Can they have a heat level of gas (bottled Orange) or accessories that must change. Is this possible? All tips this August
99% of gas appliances will have any type of gas (butane blue, orange propane), but you must change the controller (which determines the speed gas is left in the kitchen) that are only a few pounds from most camping stores and also be able to give advice on how to change thread also, apparently, propane burns much more efficiantly use less if you're brave enough to go camping in winter propane can lower stand tempreture before it freezes, I changed from blue to orange with a tent trailer and I've never had any problems, but it is easier you can get large bottles of butane as well, good luck.
