Double throw circuit breakers are only used in specialized systems. They are not used in houses or MHs.

Tandem circuit breaker.
This style is common.
Tandem breaker
Circuit breakers are the same as residential.
maybe in yours but not my 08 bus.the breakers are shorter than house breaker,s and about a inch wide and are double throw per breaker most likely referred to as tandum.they do not look like my S+B house breakers such as the pictures u listed and the mini handle that allows u to turn on and off are smaller in size
