We are newbies to the towing world. We usually throw a few ice packs in the fridge and rely on the towing battery to start getting things cold until we get to the campsite (it's often not practical to cool the fridge before we leave) and can use shore power. I understand that our 2017 MaxS battery gets charged from the 7 point tow vehicle connection. If we turn off the battery disconnect switch each time we stop for breaks along the road, am I correct in understanding that the fridge will stop cooling (fine by me)? I hope this is true as I have no desire to drain the T@b battery while in transit to the campsite. My other question: the 2017 manual says that even with the battery disconnect switch on off, the 7 point connector continues to use my TV to charge the T@b battery. Won't this drain my TV battery?
