I have the same unit, took a year to fix but is a joy when parked.
mods: CHF, f&r Helwig SB extensions, Blue Ox Trc bar, inside to much to list but the microwave is mounted wrong so pull the mounting screws, replace with bolts so they can be tightened, fix the crappy crossbar mount with correct bolts / shim as needed and that will solve your microwave noise.
