RVd for 40 years and have always run my fridge on the road. I can say propane is a lot safer than it was 40 years ago. With all the sarety devices on the tanks. I actually watched a repairman change out a propane tank without shutting off the valve. If he had done that 40 years ago he would have been toast. When I asked him why he did that he told me that is how he always changed tanks. :S
