We purchased a 19 Flagstaff 29RKWS in 2020, but before we finalized the sale, we had to buy additional steps with one handrail and purchased a second to allow my wife to be able to get in and out. We bought a 5 step add-on which works well. Currently trying to come up with a way to mount them permanently so I don't have to go through unloading/loading them from the cargo compartment...not getting any younger. While made of aluminum, they are still somewhat heavy. The fold in the door steps are nice, but no easy or solid way to attach handrails. We have a three step, but if 5 could be placed in the same space, that may work well for us but unable to locate a 5 step. Don't know how to add a pic, below is where we purchased them.
