When on inverter am I using the batteries?

When I'm parked, plugged into shore power and I'm plugged into the inverter outlet in the refrigerator compartment, is the electricity coming from the shoreline or from my batteries?

I guess I'm asking if I am draining my batteries with the refrigerator (or other appliance) by being plugged into an inverted outlet and replenishing them at the same time with the shore power or am I bypassing the batteries since I'm plugged into shore power?

Additionally, if it's coming from the batteries, should I switch to the shore power outlet to keep from running on them?

I hope my question makes sense.

Can't say for your coach and don't even know what you have, but with ours, there's a pass through feature with pretty much the whole house outlets. The exception being the block heater, which is shore only and one of the two outlets behind the fridge, which is shore only. Either way, shouldn't be a biggie and just like with our old coach and whereas I installed a separate inverter and ran some outlets. Consequently by doing this and if they were in use, when hooked up, the batteries would be replenished continually, by the converter/charger.
