Maisie, I've just seen your post. We do use our cooker on a table. You can use it on a camp kitchen if you prefer, but you'll have more room around the cooker if you put it on a table. You don't say where you're going to be cooking nor what kind of set-up you have, but if it's inside a tent, then I'd say you need to use a camp kitchen with a windshield, but be very, very careful. My parents used to turn off the gas at the big cylinder after every use.
I usually freeze the first night's meal. I have been known to cook both the sauce and the spaghetti beforehand so that I just have to heat them up when we get there after we've set up. When we go abroad I freeze the first two nights' meals (not the pasta or rice). You could use packet mixes for chilli rather than taking all the spices from home. You could use cook-in sauces for korma, cook the rice on the other ring and grill the nans, too, or just cook them quickly in a frying pan after taking the rice off the ring early and leaving it to cook in its water for a bit.
We've got an FC so our set-up's a bit different, but my DB's got a kitchen cupboard unit from Go Outdoors (cost about £30-40) to put his coffee/tea/kettle on. I would recommend that, too.
