If your spending as much as 6 months may I suggest going over to eastern europe as well. The visa for EU would be solved by popping into either Turkey and Istanbul or Ukraine. This part of Europe offers much more variety than Western Europe and nothing exciting ever seems to happen in the west when you been to eastern europe and balkan. Apart from friendly people and lower cost it is also easier to find camping since its not so crowded. Roadconditions are suprisinly close to the west as well.
