Floor Question

[TheMuffinMan-TNT]

Hey all I'm nearing the end of the design phase of my tall squaredrop-ish style camper that will have a short walkway from the door to the elevated bed that goes by a door to a bathroom (wife wants a "real" bathroom) and a small couch. The walkway is 5 ft long x 25" wide but I am trying to insulate the camper for 4-season use and plan on using 2" of probably Rockwool Comfort Board 110 which they say you can walk on or if it's too compressible for my fat butt I'd do XPS foam then ontop of that a thin sheet of metal or plywood then some LVP or something. Does that sound like it'd work for something that'd not be too flexible for an adult walking on it? I can put some reinforcing ribs through the area if I need to but would prefer not to.

XPS with 1/4" ply on it would be invincible. The floor on mine is XPS with just EVA foam puzzle matt over it and years of knees on it, no issue.
