Latest: yesterday I took out my compressor and blew air into the top of the exhaust stack best I could with 100 psi of pressure to try to blow out any debri/insects/spiders, etc. Turned on the gas and started the fridge. Left the fridge on for about an hour on gas then poked my head in the camper...still smelled gas. I'm out of ideas on this one...maybe try some Beeno?
