True, but there is the "surge" in amps when cycling start-up, so most people report they need at least a 600w inverter for the res fridge.
Our new small absorption fridge on AC has a steady draw of more like 14 amps vs the 5 amp steady draw of the small res fridge we had. I don't know if there is a surge with the new fridge on AC when you switch from propane to AC.
We prefer to use the 120v mode from inverter while on the road and then switch to propane on arrival, but unless stopping for gas or taking a ferry, that is considered safe by many. (Unless you are in a car crash of course)
It's a heating element- there is no surge, as it is the easiest load for an inverter to power. While it draws more steady state, it is just on or off- a non-inductive load.
