Hej Jeckill,
I think there is not much "Spanish scene" in that area.There is more to see around Barcelona(panscrapers).
Last year we went by car on holiday to the south of Spain(Sevilla-area,the family from my wife lives there).
On our three "3" weeks overthere and +/-5000km,I saw only one "1"! buggy(with Portugese licenceplate),and on our way home
at the French border, I saw a Baywindow camper.That was it.
So I hope you'll have more luck,and have a nice stay there.
Grtz,Peter
