I never can figure out those who have auto features and refuse to use them. I turn both tanks on and let the auto do what it was designed to do.
My wife has had automatic clothes washers for over 40 years but insists on trying to use it as if it was an old wringer washer and after every cycle twirl the control knob until they quit working.
The one tank open folks are living 40 years in the past too. Makes me wonder if they drive vehicles with the power brakes and steering disconnected too.
AND this rig has auto level and I use it too although it can be done manually.
