Sorry if you think stating the bleedin' obvious, ie suggesting asking the people who know best is nasty, you must lead a very sheltered life.  As for the comments about moving a caravan illegally, so many people on here and other forums have fallen foul of the law through ignorance or the sheer stupidity of thinking they can get away with it I should have thought it was glaringly obvious that you shouldn't do it.  If as William suggestes fgg doesn't speak either Spanish or Catalan then being pulled over by the Mossos in the middle of the night would be a seriously traumatic experience

I didn't 'google' until after William made his post so there wasn't any point in me saying anything further.  But it took less time than it would have taken to make the original post.

Fgg, if you need english spoken advice you could ask the AA or RAC in the UK as I'm sure they have many clients who caravan in Spain.
