Mine has the Power Gear Active Air Leveling, no jacks. Gives me about six inches of movement at each corner. Can lean coach to either side to top off fuel tank when I come across cheaper fuel, able to level at stops without worrying about jack sinking in hot asphalt or messing with blocks.
Factory support is excellent, had one problem and he walked me thru diagnosing it and repairing the bad electrical connection.
I like the feature where it wakes up and will relevel if needed.
