I am curious about the most economic way to travel to and through Europe and was thinking to load camping gear in a hatchback and put it on a ferry to somewhere in Europe (e.g. Lisbon) together with us inside. Because if we made the trip last over a month, it would make more sense to ship our vehicle (I heard it's around $1000 each way) than to rent it there and we could camp out of it most of the time.
Generally, is this feasible or is it just a bats**t crazy idea? Or somewhere in between.
