One my 2001 C I modified a wood ladder the ones that open as an "A", took the ladder apart cut the top portion to the correct height and placed the last rung on the ladder so that it rests flat against the bed, in order for the ladder not to move I drilled two holes on the rung that sits against the bed and installed two sliding bolts, this proved to be perfect I also found a wood towel rack that I installed on the ceiling in front of the AC just to have a hand hold for balance not as a trapeze.
This has proven great, the ladder rungs are wide side to side and front to back big enough that your feet do not hurt as opposed to the flimsy ladders sold for this purpose, I also installed carpet remnants on the rung.
