No main breaker is required. Main is required if it requires more then six operations to disconnect power.
My Pace Arrow does not have a main!
At one time that was NEC code for houses but what I remember was 5 operations max to disconnect power. Common setup was Range, Stove, Dryer, maybe one other 220 appliance then another 220 breaker feeding ALL the 120V circuits. 5 motions, turned off power.
Not sure that is still allowed by code.
None the less, If the Pace arrow has no main breaker it is definitely in the minority, the common WFCO panel as a 30 or 50A main breaker feeding the panel. And the WFCO is used in the vast majority of trailers built in the last 20 years, The others are similar with a main then the other breakers.
