Euro 2 in Europe

Hi there, I have been asked by a customer to run to France and Spain and occasionally Italy but I have a euro 2 v8 Scania. What problems will I have with regards to tolls/charges ifusing this vehicle rather than a euro 4/5?

France spain no probs or toll differences
Will change oct with ecotaxe i would of thought

Wont be able to use blanc or frejus for italy tho

Think that answers my question, many thanks
