At home we haven’t had a microwave for 20 years as it’s something that the only thing we ever used it for was jacket potato so got rid of it and haven’t missed it, when we bought current caravan it came with the microwave and we haven’t got round to using it so far, if we decided to have a jacket on the caravan we’d probably start them in it with the oven not as hot as at home, I remember back in the days we did have one we did the same as above, jug of water till it makes everything easy to just wipe out.
