Not autotransfer(That is standard and is a great addition) , rather the system that starts the gen set when the battery is too low.
Funny story regarding the lack of autotransfer on previous RV - In our old view, you had to plug in to the generator outlet or there would be no power in the house, minus the 12V stuff of course. One time my DW helped pack up and she put the power cable in the bay, but did not plug it in. Later she wanted to turn on the TV so she started the gen set and then told me nothing was turning on. Power center checked out fine, flipped the breakers, then it dawned on me that I was not the one who put away the power cable... I love the auto transfer switch.
