Battery charge question

[krgbcg]

Newbie question- can I put a trickle charger on my battery while it is still wired into the camper AND have the camper connected to a shore line ?

Yes, technically. but the trickle charger won't be doing anything.

Depending on the trickle charger, it might be able to sense the voltage, and while everything is running, the system voltage should be around 13.8 volts, and the trickle won't actually be doing anything.
