Here it is in the camper with a piece of roofing for a heat shield.
We had 4 inches of snow here at the house yesterday very unusual event. Where my son's camper is it got 10 to 12 inches of snow. We followed a snow plow when I was taking him home today. The vent going out the window is heavy duty dryer vent (the kind for running under the floor just 14$).Its set on 3 cinder blocks so I think it will be safe .
