Corinium on ferries

We have a 2019 Corinium duo which we intend to take to Spain this winter, with the long overhang and a small towbar fitting cycle rack what are the chance's things are going to scrape coming off the ferry up the incline, last week at the Berwick upon Tweed site coming off the road up the incline to the site I managed to take the numberplate off my Bosal bike rack (I've sinced raised the number plate) So, any information from owners who have done the ferry bit in a Corinium. We love the van as it has a simular layout to our old Augusta.
