Just on my first trip out and still having problems with switching over to gas when off shore power. Before it would switch over (last season) but as I traveled it gave an error message. now it doesn't even turn on to gas. I will be near the factory and thought it best to make an appointment. We will be staying in Shipshewanna and Elkhart is not that far. We are traveling short distances so the food does stay cold but it is frustrating not knowing how to fix it myself. Any suggestions.
