Has anyone got any experience about walking the Camino with your equipment on a small cart which you pull from a padded hip-belt? If you get one balanced well enough and one with wheels that roll easily it should be a good way to ease the load on yorself for most of the way. Of course there are some parts where the track is stony and where a cart would not be the best thing, but I think it could be a way of reducing the wear and tear on your knees on a big part of the Camino.
