2020 Solitude 382WB. We have a GFI outlet at the front of the sinks that keeps popping randomly. Apparently when it does it cuts off all of the outlets in the entire back half of the trailer (bathroom, bedroom, back wall of kitchen). It pops even with just a single USB charger block for an iphone in any outlet - nothing else. It also pops either within minutes of plugging it in, or up to 2 hours later. The fuses in the panel all still sit in the ON position, including the one labelled GFI on the far right.

Could this be a bad outlet tripping itself?
