Hmmmm... maybe not the best story under the circumstances, but I doubt there is any problems with your trailer meave.

Some years back, I had a 13' trailer up country. I used to bank it with fir bows. As soon as snow was on the go, I would bank snow. One day, I was sitting in a lawn (snow?) chair having an ale and smelled that smell now and again. I waited for the wind to calm out and smelled all the fittings around the tanks... nope. Imagination?

Then, I got a good whif again in the chair. I dug into the banking. A slow leak at a fitting under the trailer. The buildup of propane after several days was scarey! I made four "holes" which I would bank again at night until I replaced the fitting on the next trip in.
