Battery Charging

I keep my Winn Journey at the house and have just replaced all batteries. I am a newbie, and would like to get a battery tender. As I have four(4) batteries, how many of these things do I need. In all the advertisements they refer to 'the battery' and I find no info on stringing(paralleling)more to the one tender.

You can buy battery tenders that are designed to charge two separate battery banks. I use two of the singles, one hooked to chassis and one to house batteries. Or just use one and move back and forth. Whatever you choose.

Hi mking.
The success of my suggestion depends on if the chassis and house batteries being located next to each other. Make a jumper cable long enough to go from the coach battery terminal (where the coach charger connects too) to the positive terminal of the chassis battery (if more than one, it doesn't matter which battery you choose). If you leave your coach plugged into shore power the jumper cable will charge the chassis batteries as the coach batteries are charged by the coach charger or your battery minder.

Place a reminder to yourself to disconnect the jumper cable before using the coach.

Thanks to all, interesting concept from GaryKD. My battery trays are stacked above/below each other. Have to really look at the wiring to be confortable to not fry my components. Will probably unhook all cables except the parallel jumpers and put one tender on each battery set.
I have no 50A shore power here at the house so do not know how the on board systems work. This unit has a solar panel, but it is not operational, full of mildew or something?
