If it's a new Vegas one the GFI reset in the bathroom may help.

GFI. Circuit plugs no power no reset buttons any ideas.
How do you know it's GFI if you can't find the reset buttons?
RVs usually have a GFI circuit receptacle that also protects 2 or three other receptacles downstream of it. 99% of RVs have the GFI receptacle in the bathroom. If their is a second GFI receptacle it could be anywhere although I have seen them in the receptacle in/near the dinette.
