The original caravel
heater is essentially a stove burner in a coffee can - and when it works, it's fantastic. It keeps the trailer warm, and it's virtually silent. Unfortunately our started giving us trouble and was harder and harder to light, we were always down on our hands an knees trying to get it to catch. Then one day 'boom!' right in my face - made my ears ring! And that was the last of the heater. No one will work on them, so I replaced it with a new heater. The new heater is noisy, and uses 12v
to run the fan, so it's not as boondocking friendly. but it's safe and runs off a thermostat and works every time you throw the switch to turn it on. But still, I miss the old heater!
