They do come closer to the ground & the distance between steps is less making for a more comfortable step.
Our last unit did not have them, but I purchased them on a trip to the factory for somewhere around $150, I think. Took me around 1 hour to change out. I do have a good set of 3 steps sitting in the shop waiting on a new owner. Cheap! New suite came with the 4 step.
