Ganged circuit breakers are fairly common. They are used for inputs to power panels. In the event of a problem in a 50A setup, you would want both hots to trip at the same time. In a 30A setup, you still want them ganged so that both hot and neutral open, since neutral is also a current carrying leg. I'm not completely familiar with the 50A panels used in RVs, but in marine 50A panels, we actually use a three pole ganged curcuit breaker so all three legs trip, two hots and a neutral. In the household type panels I've seen, the neutral is not switched, only the hots, and all the neutrals go to a common buss bar for each leg.

That's why I was confused, and still am, when the OP called them main breakers and wanted to replace one of them.
