LOL--- I should explain.... the trailer had holes in floor behind the gaucho, believe me, there was PLENTY of fresh air coming into the trailer that night!
The first trailer Regina and I owned, a
1968 Utopia, had a Humphreys gas light which we used to take the chill off the trailer at night. Our houseboat had a gas light too which we used for the same purpose.
I bought one off of Ebay for to install in the Airstream --- I tee'ed off the gas line to the refrigerator but the lamp never got that "coleman lantern" burn,, I finally took it out and sold it.
When our daughter had her accident-- (horse accident, she's better now, still hasn't regained her sense of smell or taste) she lived last winter in our trailer.
she rarely ran the furnance relying instead on an 'Amish' heater and the catalytic heater. the pipes only froze once ....
Lucky she didn't have her smell as there was a broken cap on the sewer vent in the trailer (behind the false wall in the closet) and it always had the smell....that got worse when I emptied the black water.
We were at a rally and I was embarrassed to have people tour our trailer because of the smell. A fellow Airstreamer told me to check the vent piping which I did and solved the smell problem!
The trailer was drafty,,, we put bat insulation in teh trunk, under the beds and under the front credenza.
