Leaving RV MH Plugged in at Home
Had an asphalt pad done last year next to garage for the MH. Today I'm running dedicated 30 amp breaker and wireing/outlet to outside wall next to the pad. Question for those of you who have an outle...

You can leave the old single stage converter on the batteries all the time with no problems too, like we do at home. (Parallax 7355) The trick is that the temperature outside has to be within the parameters for float charging voltage (13.8v in the case of the 7355.) There is no "boiling out the batteries" at 50F or less with 13.8v.
Some "three-stage" converters float at 13.6v, not 13.2v, so in summer the 13.6v might be a touch high where you are. 13.2v is for 80F, too high for 100F
If your float voltage is too low for winter time in many places, like 13.2v with a PD, then you won't boil them out, but you might not be keeping up with self-discharge either. Also the little shot of 14.4 every so often may or may not keep stratification at bay.
So--IMO there is no plug in and forget with any charger anywhere- you still have to keep an eye on how things are going and take any corrective actions when you are floating the batteries. If they are not connected to a charger at all, you have to keep up with routine charging sessions instead.
