Yes, look in your manual. Mine states the battery is charged by the TV whether the battery switch is set in store or use position. Read it last night.

Keep in mind that charging from the truck will take many miles to re-charge depleted batteries. Modifications in the wiring can be made that will permit much more efficient charging but with factory truck wiring it will take awhile. I had dead batteries a few years ago and it took several hours of driving before the refrigerator would start cooling and I think that's only about 4 amp usage.

Yep, although for some trucks you have to add a fuse or hook up an extra wire or something for it to work.

In practice I find that I get around 10 amps per battery this way, so it takes 10 hours of driving to go from completely dead to fully charged. Still, it makes a difference.

It does, and as noted, it takes a lot of driving to recharge your trailer batteries. If I boondock and I've driven all day, I still run my Honda 2000 for an hour or so to make sure the batteries are topped off by the end of the day. I don't think I'm a power hog, but the fridge, etc draw the 12V....and I have an inverter so I'm known for watching some TV so I know what's going on in the local world!

I've never had an issue with a complete recharge while driving. BUT!!! I run a big fat charge line with a self resetting 30a breaker direct from B+.
