As said previously mentioned your chassis batteries are probably not charged while on shore power and parasitic loads are draining them. Google LSL products and take a look at the Amp-L-Start or the Trik-L-Start. The amp-l-start is a little more heavy duty but either will do the job. Very simple install and excellent customer service. After initial install it will take a couple of days for the chassis batteries to charge up but after that they will always stay fully charged as long as you are plugged into shore power and your inverter is functioning properly.
I installed the trik-l-start 6 yrs ago and have never had a problem again.

Correct. Batteries drop a little each day. So a trickle charge on the chassis batteries is the best bet. I use a
Battery Tender during the winter. Now if you're house is connected to shore power already, you can probably plug the trickle charger in from inside your RV and run the wires to your battery.
For yor house batteries, you should find out if the built in charger is a multi-stage charger. Multi-stage chargers will drop down to a trickle charge when the battery is fully charged. Single stage chargers can overcharge and damage your battery bank. There are upgrade kits available if you have a older charger. I upgraded mine (
