PM,
I leave mine in both. The only time I switch is if I am running the live well with the engine off. The batteries will technically not get charged at the same rate.
The best overall solution is to install a battery isolator. This way you can leave the starting battery just for the engine, the deep cycle just for the aux. The isolator will charge which ever battery needs charging. However leaving the switch in both makes it one big battery on a 1,2 both switch. Best to have a fancier swicth or 2 independent switches with means to parallel just incase you need it. Only down side is there is a small voltage drop on some isolators. Not a big deal. But this does create the problem of more wires. I am a firm believer that fewer wires in a marine enviroment the better.
