I can potentially take one down to the Pyrenees with us in a couple of weeks.
Although I am not sure what I would put in it. My worry would be security.. although I guess the answer is to not put anything in that you can't afford to loose.
Does it have a pocket for the reflective square panel? (in Spain and Italy any overhanging loads must be indicated by a square panel measuring 50cm x 50cm with reflectorised red and white diagonal stripes which can be purchased from Fiamma stockists (www.fiamma.com). Panels are available in aluminium and plastic and in Spain you can use either however, in Italy the panel must be aluminium)
