You know last year I saw a foto what someone had done to their AS to make it wheelchair friendly but can't remember if it was here on the Forums. Try the Search 'machine' with 'wheelchair' or 'handicap'. Depending on the vintage and length of the AS that you find I would be cautious about hanging ANYTHING from the rear of the trailer.
