Hi Jim
I will agree with Mr Evans, your best route to Como is through France & Switzerland. Many years ago when I was trucking I used to tip in Chiasso, and reload in Como and if we were under 28 tonnes gross on the out trip always went that way, saving a fortune in tolls.
As I said it was some time ago, before all the motorways there are now, were built. But I see they follow the route we always took and they were good roads, even for a 40 footer.
If you look at the route we took you would enjoy it or you could go on the Autoroute as and when you wanted to get on a bit, if you find yourself doing too much sightseeing enroute!!
From Calais we used to go- St Quentin - Reims - Bar le duc - Nancy - Colmar - Mullhouse -Basel(Swiss) - Luzern - Sellisburg Tunnel - Gotthard Tunnel - Bellinzona - Lugarno - then into Italy at Chiasso, Como is then about 15/20 minuets.
The run down thro' Swiss is fantastic and worth every penny you pay for the 'vignettes'which I think you can get thro the AA or RAC, about
