The pilot light 'going out' on the Buddy Heater is the low oxygen cut off kicking in - not good! This means your are at risk of CO poisoning. Do you have a CO monitor? Did it go off?Mr. Heater or Camco Wave-3 are your best options.
I've used both in my camper. The Buddy Heater is awesome for providing heat really fast. Even on the coldest of days the camper is nice and warm in 15mins. The downside is that it can actually get too hot. I've also had issues with the pilot light going out. The heater would run find for about 10mins but then it would go out and not work for a few hours. Some people say you need to clean the pilot light piping because condensation builds up.
The Camco Wave-3 isn't cheap but its great for a small camper. The cool thing that I like about the Camco is how it creates heat. Instead of having a flame it uses a chemical reaction. It does take longer to heat the camper but I feel safer using it in such a small space. Also the settings are better for what I need. The high setting on the Camco puts out the same BTUs as the Mr. Heater on it's low setting.
Rando, yes I have a CO monitor and it did not go off. When it happened the first time I thought the same thing so I exited the camper for a few hours to play it safe. When it happened again I took the heater outside and it did the same thing.The pilot light 'going out' on the Buddy Heater is the low oxygen cut off kicking in - not good!

The non-vented heaters (Wave, Buddy etc) are really not a great choice for regular use - there is a safety issue with Carbon Monoxide/Oxygen depletion and all the combustion products end up in your living space, making condensation issues far worse. Vented heaters (Propex, Truma etc) keep the combustion products outside - are much safer and produce 'dry' heat.
