Inverter and mains (shore power) with common ground

I have a small trailer with shore power (120v ac) and an onboard inverter (12v dc to 120v ac). I have a manual transfer switch between the two so that only one can be feeding the trailer at a time. The transfer switch only switches the hot and neutral leads. Is it okay for the two grounds to be tied together (bus bar)?
Thanks!
Bob

Yes you may tie the ground wires (equipment grounding conductors) together.

Ground wires are all tied (bonded) together wherever they come together -- in junction boxes, etc.also.
