Battery Maintainer
I used to leave my motorhome plugged in all the time and let the onboard charger keep the batteries charged. But I found myself having to replace the house batteries every couple of years as I think ...

The main ones I'm concerned about are the chassis batteries. Since the house batteries can be disconnected with a switch they tend to stay charged between uses, but the chassis batteries die even with the battery tender I use. The one I use isn't the cheapest, but it isn't the biggest either. The one I have is the Battery Tender Plus and it is 12 volts at 1.5 amps. So clearly it's too small to maintain the two chassis batteries. Sounds like the ones that connect to multiple batteries are out since I'd have to disconnect batteries to use them.
This one is a 5 amp model so you think it will keep the two big batteries charged? 12 volt 5 amp Battery Tender
