Modify OR Access Easily Over cab Bed for the Older Camper

I think the OP meant that they couldn't use any type of ladder safely. If their RV has a rear dinette that converts into a full bed, that might be sort of a solution. It is a pain to convert dinette to a bed, add covers and pillows, and convert it back in the morning. Consider buying a 27 foot motorhome with a rear queen bed or separate twin beds. With a bedroom slide, you can have access on both sides of RV queen bed for ease of egress and access during the night.
