The promariners are designed to be plugged in and left. The main cranking bank will likely not need any charger between uses, and the charger will sense this. Depending on use, the house bank may or may not need recharging.
Let's assume that I have everything wired correctly and don't have any "parasitic draws". Is there any problem/harm with leaving my perko in the 'on' position for one of my battery banks? (leaving the switch set to "2" while plugged into the ProSport)
