We pack one of these along with us in our small Class C RV, along with a 20 gal propane tank to fuel it for many hours, so no need to find or carry along wood.
It has bricks that get hot from the flames and then radiate heat for great warmth while we sit around it. We can also roast hotdogs and marshmallows over it's hot bricks and flames.
We haven't found any camping places where use of a propane firepit isn't allowed:
