I just did 1800 miles down to Florida. I usually keep food in the fridge cool running on gas while traveling. This time used 12v option. After 800 miles stopped at camp site. Found tab batteries low. Plugged into site power. Charged in morning. Checked trailer connections to tv seemed ok. Did 1000 more miles. After 500 miles checked tab batteries, found Half depleted. Switched to gas. Any idea if it is normal for the TV not to charge the tab batteries? I have seen a post about adding better charging but not sure if that's because there actually isn't any.
