Hi All, I have a quick question. I have a 2013 Heartland Trail Runner SLE 25 FT Trailer. After storing it for the winter, the trailer no longer runs off the battery. Everything seems to work fine when plugged in AC. When I disconnect the AC power, nothing runs on DC. I checked the inverter and don't see any blown fuses. The only other thing I can think of is switch I am missing that may be turned off. Or possibly the battery is too low?? Although when I have everything hooked to the truck, the lights will not come on, or power to anything else. Any Help\suggestions would be greatly appreciated. Thanks, Gary
