Not disputing salt on the roads in winter if you want to drive in snow and ice it can be avoided with a motorhome personal choice - i'm saying a fairly open deck ferry puts a vehicle in a very salty enviroment similar to using a jet washer on low pressure and using sea water to wash it - and the salt will get everywhere with wind behind it - and that it will help with a vehicles corrosion - just look at vehicles that spend their lives on seafronts compared to one that spends most of it's life inland - certainly most vehicles spend more time parked than being drivenA bigger problem surely is the use of salt on the roads in Winter...
