Breakers are not switches. Each time you turn them on and off you reduce the load carrying capacity. Won't be much but if done frequently a breaker can lose 20% of it's capacity.
There are breaker/switches that can be used this way but probably hard to find for RV's
Sorry, but that is not correct. See what I just posted
here. Breakers in an RV panel can be mechanically operated thousands of times up to their ratings except a breaker that has tripped on short circuit or has repeatedly tripped on overload will have it's life expectancy significantly reduced.
There is no reason to turn breakers off in the panel inside an RV. Personally I wouldn't ever again leave a WFCO on and maintaining a battery(s) over the off-season due to the one we had that failed and also damaged the battery. They have a bad reputation and we found out the hard way. We now have a PD converter/charger (and AGM battery) and have no worries about leaving it on year-round. If you have a WFCO, I'd disconnect the battery and use a battery tender. If no 120 VAC available, consider using a solar setup which are now rather inexpensive.
