Funny, I was thinking the same thing.  

Glad you asked for more details.

I tried hard to get a trickle charger set up on my batteries to preserve them.
 Not all the chargers are created equal but I didn’t thing there was harm to a trickle charger. 

Now looking for a charger that can stay out of sight in my bus and either fast charge or trickle charge depending on the need. Have plugged in so that once I connect to shore power it just works.

But, I certainly hope my current system does more good than harm.
