A friend of mine has a '99 or '98 Patriot Thunder with a custom ordered mid-door configuration. Because his DW uses a wheelchair (cannot walk or lift herself - paraplegic) he had a power lift put on the entry door. It has a trapeze that she slides onto from the wheelchair outside and is then lifted up into the coach. I don't remember for sure how she gets around when inside the coach. I know she does travel from end-to-end inside the motorhome and sleeps in the big bed in the bedroom. Therefore, she does have some way to be mobile, but I am not sure if she has a special, narrow-wheeled wheelchair or a wheeled ceiling rail with another trapeze.
