Here's the entry well step and hand rails I added to our 2860DS.
Sounds like your inspired to add a step to make it easier to get in and out of your new recliners. Btw, the leading edge of my raised slideout room with the dual recliners on it is hefty lumber and I believe will easily accommodate fasteners for a cantilever or other step stool design. I sort of envision it being fairly lightweight yet plenty sturdy anyways.
Well, here's the entry step I added and the handrails. It's all pocket screw and glue constructed. Entry step doubles as storage with piano hinged top. For the handrails I found the dinette back and seat was very easy to open up and 1x6 pine boards were added as handrail backers as well as a few metal L brackets to keep it steady.
We love both mods. The step height in the entry well was over 10", now it's about 5". Did have to give up some foot placement space but worth it. Attached by 4 heavy duty velcro hook and loop tapes and it hasn't budged in 3 seasons but would be removable
I did the handrails for my wife but I find myself using them all the time getting out especially
