I have honestly never sweated blowing the breaker for the campground.
The thing to watch is the heat creating appliances, water heater, toaster, coffee maker and hair dryer. You can predict when the coffee maker , toaster and hair dryer are on so don't put them on at the same time. It is hard to predict when the water heater is running and I'm guessing the AC isn't running first thing in the morning.
Here is a good video for the level up system. Note they have a few varieties out there and for me I think the controls user interface is pretty flawed. Setting up is easy. Front jacks , remove trailer then hit "Auto Level".
When leaving I never remember the two buttons to press to go to the "Auto Hitch" height. Instead I go to the manual mode.
Learn the manual mode. It goes as follows--- turn on unit, hit up arrow and menu says hit enter to go into manual mode. Then you do front jacks then either side while watching the level meter. When you want to retract hit retract button.
