We have the usual oven, hob and microwave in our van and also sometimes take a small slow cooker for when we are away in the winter in the van, we also have a small low watt air fryer that we have just bought for the van, we have an air fryer that we use most of the time at home and saves the hassle of using the family oven that can take ages to heat up when there is only the two of us at home. We don't have a gas bbq though we have a small charcoal bbq for the summer months this set up works for us.
