Thanks for chiming in on the step issue. I crushed our step entering a highway from a pull-off site in Sept. 2024. So badly that the dealer decided it had to be replaced. $940 for the step plus $230 labor.
With new step I drove the 29XK just 4 short trips between RV shops here in town. Leaving the last shop, I drove from paved parking up a very slight incline and scraped the new step too. It surely didn't look like a 7+ inch clearance problem. But when front wheels dip into the street, clearance at the door shrinks quickly. Got home to discover one side of step housing was bent enough to prevent the step from full extension.
Perhaps the bend might have been removed, but by then we decided to unhook step wires to prevent its motor from burning out with the strain and just stop using the automatic step. I don't want repeated repairs. We bought a plastic stool we now carry in the door well. It works fine.
