I got my TT which doesn't have an isolation switch on the battery. The salesman just said that if I was going to be parked for more than a few hrs, at a time while hitched up to just unplug from the TV so that trailer use wouldn't draw from my truck battery. I've since installed a solar panel on the roof and my question is... If my trailer is hooked up to my truck, will the solar panel be charging both the trailer battery as well as the truck battery?
