Hi, my name is ***** ***** I have been in the home improvement and repair field for 20 years. I will be very glad to help you today. There are a couple possibilities to the cause of this issue. The most likely is simply that the gas bottle is not seated well. The next is a bit more complicated. The thermocouple that senses the pilot flame is needing to be replaced. This can be a bit difficult depending on the configuration of the caravan. It may even require disconnecting the gas connection to the fridge and removing it to replace the thermocouple.
