Hello folks! Just got a 29' jayco (swan?) pull behind. I'm gonna just use at hunting club but, I'd like to fix a few things before carrying up there. I've got no lights that work inside except some plug in fluorescent lights. All receptacles work though. Any clue as to what might be the problem? I do have a leak around ac that I'm gonna fix this week too. Ceiling around ac is sagging so, it needs replacing also. Thanks
