I think the recommendation to run the engine while levelling is to prevent a big hit on the battery. Our four previous MHs all suggested running the engine while levelling. Also, the jacks would not go down or up if the parking brake was not engaged.
We don't have levellers in our 5th and current MH and I have to say we don't miss them. But, to put the slide out the parking brake must be engaged.
We've had both HWH and Power Gear systems as well as 4 jack and 3 jack systems. With auto levelling just hope the control unit never goes wonky since it is then difficult to determine what it thinks is level. I'd be inclined to stand close to the door to be able to turn it off in case it develops brain fade.
We also made a point of keeping the recalibration instructions handy. When the batteries are turned off and it is in storage it might well lose its calibration.
