I have a 2015 elk ridge 38rsrt. We were having electrical issues and it turned out to be the battery charger, so we replaced it. Everything worked great after that. Three weeks later, the electrical are back but not as bad. The charger is working and the battery is holding a charge. The refrigerators are malfunctioning and so are the air conditioners. Has anyone else experienced anything like this or know what the issue might be?
