Mr Buddy heater question

I can't see the danger or problem?.. When the heater is on low or high the pilot light remains lit doesn't it? At least it appears to on mine. I leave the pilot lit on my water heater often during the winter and it keeps the water very warm (even heats it up after a few days!) which keeps the under sink area of my camper warm enough to not freeze. However, if the low setting does get your RV too hot I don't really think the pilot would heat it enough, but I've never tried it. I would most certainly NOT leave it on all night while I slept though.
