The batteries are charged by the built in three stage charger on the AC/DC distribution panel. I do plan to use some type of isolator so the coach batteries can be charged while driving. Don thanks for the link, I had not seen that Bluesea model in my internet searching. It has some nice features like being able to get a boost from the coach batteries to start the truck in cold weather. I need to do a bit more research. One issue is the distance between the truck batteries and coach batteries vs the size of the required cables. My old Itaska had a spring loaded switch on the dash that you could hold and get a boost from the house batteries. I once had low, ok dead house batteries and I used a broom to push the dash switch and was able to reach the generator switch and get it started with the truck battery.
