Plug in a lamp in the outlet to see if you have power there. You may have a Ground Fault Interrupter (GFI) plug that has tripped. Check all the GFI outlets, bathroom, kitchen, outside outlets and some not so obvious (under the table). There should be a little button between the plug outlets that should be flush with the surrounding surface, if it is raised up it is tripped. Just push it in and it will reset. The way they wire RV's it could be any where. Any outlet downstream from the GRI outlet will be affected.
