Hi, Eightyfive.
Thank you for your interest in VIM16.
I visited Portugal with my Varadero last year.
Do you usually drive motorways, or do you prefer smaller roads?
When you come to northern Germany, you have to decide ferry or road.
I prefer to use a ferry between Germany and Norway, or between Denmark and Norway.
Otherwise you have to cross two quite expensive bridges, one in Denmark and another between Denmark and Sweden.
The cheapest ferries sails between Frederikshavn and Oslo (

Gasoline is almost the same in all countries, but Denmark is cheaper than Norway and Germany.
In Norway motorbikes don't pay road tolls and there are no road toll in Germany, Denmark or Sweden.
Good luck with your planning.
Erik
