More important than the odor is the leak itself. You must fix it now unless you want to blow up or have your trailer burn down. Do you know where the leak came from? I read that you were contemplating repalcing the furnace. Did you loosen a gas line or have you kinked and cracked a line?

Howdy.....Sam's sells a product called ODOBAN..comes in a gallon concentrated jug. Since finding this product, I have NOT found anything that it could not remove the odors from including an ice chest full of rotten fish!! Good luck....blessings...Callie
