I agree, I like our Little Buddy heater.

We tend to use ours in the extreme shoulder seasons, as true winter camping
around here would involve driving on salty roads, but we�ve used it well
below freezing. As others have said, plenty of heat.

Condensation is a concern, as is fresh air, but these are solved with a
cracked window. Though the Little Buddy has a built-in oxygen-depletion
sensor which shuts the unit off if needed, we still use a common CO detector
as a backup, and we never actually seep with the heater on.
