I am having the exact same issue, except it also happens when I flush. I replaced the stock vent cover with a cyclone vent cover. I haven't used the camper yet since i installed it but will be using it for 5 days later next week. I hope someone posts a reason for it, it makes it extremely hard to be in the camper when this happens.
