I have purchased a used 2004 Rockwood Freeedom popup camper, model M-1980. I have purchased an owner's manual from the manufacturer, but it does not have information regarding the refrigerator. Can anybody tell me how the refrigerator works? How do I start it? The refrigerator in my last camper worked off of the propane tank and there was a place to light the pilot, but I do not see anything like that on this camper. Thank you in advance to anybody who can help me!
