Planning a trip to Italy and Croatia next year and was thinking about the LEZ. I checked through the british site and found that my 2002, 3.5 ton diesel motorhome is acceptable here. I then tried to check through the Italian site and met all sorts of differing rules that I find impossible to fathom out. They seem to have titles for classes, eg, Euro 1,2,3 etc... Has anyone traveled this route in a motorhome using similar criteria that could offer some advice please. I have already considered, don't go, take a different route etc. Thanks.
