the smell will be when you walk into trailer. it is stronger right at the bottom of oven which is just above heater. I took off the access panel to heater and could smell it in there.
I went and checked the propane tank, it is not real full. I switched tanks, and will check later. so far no smell.
I also suspect that the pilot on the stove might be leaking a little even though knob is off. even with pilot in off position, when I put a match near it, I could hear a little flutter. not enough to light though
