The Iveco agent replaced the big old aluminium casting which is the alternator and ancillaries support, belt tensioner and belt itself at, what we think is quite a reasonable cost, 360€. So it could have been a lot worse!
Anyway we retrieved to van and carried on with our travels stopping at the Aire at Benicassim for the night.
From there it was just a couple of hundred kms to our Spanish base where I can now settle down for a while and update the Club Motorhome website with all our new stopovers.
A trip to remember!
