I've booked our Eurotunnel crossings to go away mid-March to mid-April to travel down France, into Spain, possibly into Portugal and/or further down into Spain. We have 2 x leisure batteries and a solar panel and to date have never had a problem getting anywhere near low on power so we don't particularly want to be cooped-up on campsites and although we know how to get/do stuff in France and Germany we would appreciate advice on the following for Spain and Portugal as it is 'alien' to us: What do you do for fresh water? Similarly, what about grey and black waste? Is it easy to get LPG to top up our Gaslow bottle? Any other advice for first time winter campers abroad would be appreciated too!
