Has anyone out there ever bought a step for there 15 passenger van. Our church just got a new van so our elders in the church will ride in this one so they need a step to get in the back door. I have been trying to see if that is a option that you can get when you buy the van and if so dose the parts department list it. I have seen a kwikee 40 series double step and a single step to that seems like it will work but just wanted to see if there was one that came standard.
