Hi DBram2019,
Are you certain that it's just these 2 outlets that are in the island and that EVERYTHING else is ok? Sometimes on 50 amp service, you can lose 1 of the 2 power legs. If you're not using A/C units, or all other appliances, it's possible one leg may be out.
Also, although there's usually a single GFCI outlet, located in the bathroom, it's possible on some floor plans that there could be a second one. Take a flashlight and visually check every outlet, including outlets on the bottom of cabinets.
Often, power is routed along the frame, to a junction box that may be mounted under the slide on each side. From one of those boxes, it may go to the island. A loose connection inside a junction box could be the culprit. Be careful working on those junction boxes if you have power to the coach. You might want to shut power off before opening to inspect. Or use a $20 non-contact voltage tester (local hardware store purchase), to check that it's not hot before touching.
In the main circuit breaker panel, a breaker may trip and move only slightly. Visual inspection for a tripped breaker is not always effective. Better to flip the breakers OFF and back ON.
Good luck with it.
