disposal and dishwasher are a fixed appliance and normally on dedicated circuit. They should be hardwired to house wiring.
current code requires them to be on dedicated circuits, but not necessarily hardwired. In my case the instahot, disposal and dw are required to be on seperate circuits. but only the DW is hardwired. instahot and disposal each have their own circuit and individual outlet. and these are not required to be on a GFI. GFI is required for the accesible kitchen outlets.
but lets get back on track helping the OP figure out why his trailer is popping a GFI.
