Electrical question

[ginaseven]

I plugged in to 110 tonight to turn the fridge on and have lights to start packing.
My microwave numbers are lit and my CO detector is lit but nothing else works.
No lights work, the fridge "check" indicator comes on.
12volt lights do not come on either.
Thoughts??
Where do I start?
We leave Wednesday for a week long trip, go figure, so not enough time to get it into the shop.

Thanks in advance for your help!

Start with a volt meter. I suspect you have an open GFCI, either in the house or in your RV.
