Francesca - get a grip, my comment has ABSOLUTELY NOTHING to do about a man expecting sex.
Nothing about this trip includes any benefit for this man to do and be all these things for her during the trip. What does he get other than "a free ride" to a destination not of his choosing during which he gets to do whatever she considers "doing his share", "training", "keeping her company"? It's not a "drive straight through" type trip that would get him to the final destination fairly quickly on a tight budget. Every stop will be based on Ann's "dream trip".
My point is that if she wants to find a traveling companion who will join her for the joy of seeing the country, then she's going to have to let go of some of her dreams and be willing to compromise on the details of the trip. Including maybe finding another woman to travel with instead of a man. And perhaps identify some areas where she will be willing to meet the companion's comfort level and ideas on how the trip would play out (such as showering, sleeping arrangements, etc.)
