I have a 2008 Adventurer and the GFI outlets for some of the circuits are daisy chained.
When the first one trips at the outlet, all the other outlets will quit also. I just have to reset the tripped one, and all is good again.
Hopefully that's what you have happening.
Look at all the outlets for a little button to push. There are 2, one to reset, and the other to test.
