RV Repair: no lights on drained batteries., desert fox, gfi outlet

Question
I've got an odd one. I used my desert fox 24as last weekend and was hooked to park power over the weekend. After returning home and hooking back to the power at the house I noticed after a few days that the lights in the trailer were extremely dim. The battery is now dead. The microwave gets power but the fridge does not. Any help would be greatly appreciated.

Answer
Hi Justin
 There are a few things to check. Find the GFI outlet and see if you need to reset it. Also you should look for a 30amp 12 volt fuse near or on the 12 volt converter. Both of these things can cause that problem. Let me know what you find. Good Luck.
